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]] 422 + 423 +== IGU 16HR-3C == 424 + 425 + '16HR3C': {'poles':[(-22.211059+22.217768j), (-22.211059-22.217768j)], 426 + 'zeros':[0j, 0j], 427 + 'gain':1, 428 + 'sensitivity': 257019225.55108312} 429 + 430 +[[X axis is samples (.01 s), Y axis is velocity (m/s), 0.5-5 Hz filter>>image:IGU16_Z_huddle.png]] 431 + 432 +[[X axis is samples (.01 s), Y axis is velocity (m/s), 0.5-5 Hz filter>>image:IGU16_N_huddle.png]] 433 + 434 +== IGU 16-1C == 435 + 436 +The 1C nodes seem to have a slightly different response to the 3C (TBA) 437 + 438 +== BD3C-5 == 439 + 440 + 'BD3C': {'poles':[(-1720.4+0j), (-1.2+0.9j), (-1.2-0.9j)], 441 + 'zeros':[(14164+0j), (-7162+0j), 0j, 0j], 442 + 'gain':1.69726e-05, 443 + 'sensitivity': 702651512.6046528} 444 + 445 +*image TBA but they have been created in the past~-~- we are 100% confident our published responses are correct 446 + 447 +== Horizontal noise & how to avoid == 448 + 449 +The 5 Hz nodes are susceptible to horizontal noise due to the placement of geophones in the units, **but this can be mitigated by completely burying the units flush with the ground.** In the below example, the node was set on the floor of our basement set on its plastic carrying case support.
