36 36  
37 -Be sure to set the channel types to Seismic and the gain appropriately. For active source (i.e. explosions) you can leave the gain at 0, but for passive experiments some gain is purported to be helpful (although we have found this to be somewhat negligible). We can confirm that 6db for the broadband nodes and 24db for the short period works well.

40 40  
41 -In newer versions of the software there is a "power consumption" setting.. we are no sure what this does exactly, but the manual says it gives life a "boost" at the expense of about 3 db of resolution. Until this can be quantified a bit better it is not recommended.

49 -We recommend that the 16HR-3C be set to a gain of 24db for passive experiments and no higher than 250 Hz sampling rate unless there is an explicit reason to do so. The BD3C-5 should be set to a gain of 6db (which is the maximum allowed) for passive experiments (or 0 db if active).

54 +The GPS antenna is at the top and center of the unit, and will (usually) only receive signal with a clear sky view directly above.

63 +Both nodes take about 6-8 hours to charge from flat and hold their charge reasonably well, however you may benefit from a "top up" charge immediately prior to deploy. The instruments should last around 30 days per cycle (recording at 250hz) with GPS on cycle on and bluetooth disabled.
67 67  
68 -If you are short on magnets, you may find it easier and a lot cheaper to buy magnets in Australia. AMF Magnetics is a good retailer, and [[this item>>https://magnet.com.au/collections/shop?q=23012B]] seems to work well. It is also advantageous to use smaller magnets and store/carry them individually in your back pocket (as well as stick them to various places in your field vehicle, etc).
65 +Upon retrieval, the instruments should not be stored flat as this will damage the batteries. It is recommended to charge them back up "to orange" such that they are charged around ~~50-60%. This is also acceptable for shipping.
69 69  
70 -== Animal-Proofing ==
71 71  
72 -We have experienced interference from animals (foxes, dogs, goats) digging up and carrying nodes off for tens or hundreds of metres. It is helpful to minimise human and food smells (particularly on the rope handles) when working in areas where this is a risk. Or, wipe down affected nodes with 50-80% methylated spirits if extensive handling can not be avoided.

270 -== Connection tips: ==
271 -
272 -Connecting SmartSolo nodes to their harvesters and having SoloLite recognise them can be a bit tricky, here are some tricks to help register and program them easier:
273 -
274 -* Place the node on the harvester gently, then firmly press it down onto the pins.
275 -* Place all nodes onto the harvester before trying any troubleshooting, as they may not show up while the SoloLite software is running. Once all are connected, try restarting the software for them to be recognised.
276 -* If a node is refusing to connect, try it with another slot. It is easiest if you place all 16 nodes on the harvester, and swap any nodes that refuse to connect with each other.
277 -* Nodes will likely not show up in the order that they should, though this is not an issue. E.g, a node in slot 6 on the harvester may show up in port 13 in the SoloLite software. Annoying, but it doesn't matter so long as you keep track of what's been harvested!

281 -== Node Registration and Software Setup ==
282 -
283 -1. (((
284 -**Registering Nodes in the System**:
285 -
286 -* To begin, register the nodes in the system so the software can recognize them.
287 -* Navigate to the installation folder of “SmartSoloApps SoloLite”.
288 -* Right-click on deviceconfig.exe and choose “run as an administrator”. Save the file to the “deviceconfig” directory (refer to the snapshot below).
289 -* To avoid double registration, replace the file each time you register a new node.
290 -)))
291 -1. (((
292 -**Creating a New Project in SoloLite**:
293 -
294 -* Open the “SoloLite” software.
295 -* Go to “File” and create a new project. Don't worry about finding the exact 16 nodes used in script writing.
296 -* Ignore the settings for seismic recordings in the subsequent window. Resetting instruments (e.g., sampling rate, gain) requires reprogramming via script.
297 -)))
298 -
299 -== File structure ==
300 -
301 -There are essentially three main folders where relevant PROSPECT and PROJECT DATA is stored. Individual projects will be found as subfolders in these.
302 -
303 -=== SOLOLITE ===
304 -
305 -This folder stores SoloLite config files and parameters. Nothing too important stored here, you can always start over and re-create this.
306 -
307 -=== DCCDATA ===
308 -
309 -This folder stores the RAW data you have harvested from the nodes. The data will still be on the nodes (unless you erased it) in case of emergency, but regardless, this is the folder you want to back up and save somewhere.
310 -
311 -If you had a weird time harvesting a node, you can always manually copy it as if it were a USB stick and place it into this folder manually. The structure is: //C:/DCCDATA/prospect_name/project_name/SERIALNUMBER/label(usually a timestamp but can be anything)//
312 -
313 -Then in the SoloLite software, go to tools > Reanalyze Seismic Data
314 -
315 -=== SOLODATA ===
316 -
317 -This folder stores **exported** (e.g. miniseed) data. It is structured similarly. If your DCCDATA is intact, this can always be re-created if need be.
318 -
319 -
320 -== Data Downloading Process ==
321 -
322 -1. (((
323 -**Initiating Data Download**:
324 -
325 -* Once a new project is created, the Data Transfer View panel will display connected nodes with details like series number and data size.
326 -* If “Prospect not matched” appears, it simply means the new project doesn’t match the original programming project. This is not a concern.
327 -* Select all nodes and right-click to “force download”. This starts the download process.[[image:Smartsolo harvesting #4 copy.png]]
328 -* Completed downloads will appear as new folders in the Downloaded Data panel.
329 -)))
330 -1. (((
331 -**Exporting Data in Readable Format**:
332 -
333 -* Go to the “Tool” menu and select “export seismic data”.
334 -* Tailor other parameters to project preference and ensure "Sample Interval" matches the setting used during node reset (note: the standard used by ANU is 4ms, or 250hz)
335 -* (% class="box warningmessage" %)

338 338  )))
339 -* Set "Remove Gain" to the same decibel gain as during programming. By default ANU sets this to 24db for short period nodes (a scaling factor of 15.848932), and 6db (a factor of 2.0) for broadband nodes.
340 -* Set "Remove DC" to "Yes" to centre the data around the zero value
341 -* Set the correct Start Time (UTC) and End Time (UTC) of the project to prevent the unnecessary export of older data
342 -* [[image:Smartsolo harvesting #9 copy.png]]
343 -* Click “prepare” followed by “run” to start reformatting. Monitor this process in the small panel at the bottom left.
344 -* The data will be exported to the SOLODATA folder. For a windows system, the following file explorer page is where you must navigate to to locate your project folder[[image:Smartsolo harvesting #8 copy.png]]

349 -See [[5Hz Node Polarity Issues>>https://auspass.edu.au/xwiki/bin/view/Data/AusPass%20Data/#HSmartSoloNodePolarityIssues]] for discussion. If data is headed to AusPass, we prefer to invert the IGU-16HR channel data manually rather than in the SoloLite software or inverting the response metadata.
196 +Start and endtime: the system will automatically find the earliest time of the data and set that as the starting time. However, you can set the time a day earlier with a sharp start of 00:00:00. In this case, all the outputted data segments will be 24 hours long starting from midnight.

355 -Not so much a //bug// as much as "a thing that can happen if your SoloLite installation is corrupted". If you notice your data has large constant time offsets, you should suspect that the number of leap seconds has not been accounted properly. There is a file "smartsoloconfig.xml" that needs to be present in "C:\SmartSoloApps SoloLite" (e.g. the main program directory) that dictates the leap second offset for the last two data ranges. Since 2017-01-01, this is 18 seconds. At some point in the next few years it will be 19 seconds.
202 +Check the data all have been converted to miniseed correctly 
356 356  
357 -If this file is missing, just create a new one structured like so, name it "smartsoloconfig.xml" and put it in your main program directory. Then, Reanalyze your data (tools > Reanalyze seismic data) and your data should have the correct time. You can also do this manually, if you want. The offset is 18 seconds precisely.

435 -We are aware that there are various different published responses for these instruments and trust very few of them. One has to be careful with how polarity is handled between groups as well, and if one is working in integer counts (the ANSIR default) or mV (unclear why anyone would use this as it makes file sizes enormous). The response information published below is in **counts** and seems to fit well in huddle tests. Note that the response is the same for all channels and all units (e.g. there are no bespoke calibrations!), all appear to be sample rate insensitive, and the IGU data has been inverted (multiplied by -1) as described here: [[5Hz Node Polarity Issues>>https://auspass.edu.au/xwiki/bin/view/Data/AusPass%20Data/#HSmartSoloNodePolarityIssues]]

24 -# the start/end time is not critical, but good to have. what IS critical are the times of instrument changes as this potentially affects response information
25 -# to mark equipment changes, add a new line with an updated start date (e.g. AKL05 above)
26 -# can use tabs or spaces, but spaces tend to look nicer. formatting ultimately doesn't matter too much so long as there is any sort of "white space" between the fields
27 -# if you don't know a serial number, put 999. if you don't know the elevation, put 0
28 -# for Nodes, put the same serial number for both Recoder and Sensor (since they are the same!)

1 -I can verify that the default orientation for the SmartSolo 3C nodes is positive values for case motion to the South, West, and downwards. We have co-located nodes with permanent stations and noticed this correlation when comparing waveforms.
