# Calibration file for PRR-620 Spectroradiometers on OASIS Moorings # Model PRR-620 # Serial 9619, Calibration date 17 Jan 2003 # File created 30 Jan 2003 by Dan Cosgrove # # This is calibration file for one PRR Spectro # Format of this file was chosen to be consistent with Biospherical cal file # # There is one line of calibration data for each channel as follows: # bank chan type name a b c cmin cmax units # # bank: Bank number, i.e., the address tag for a given bank of channels # chan: Channel number # type: Type of channel, as follows: 0 = unused, 1 = down irrad, 2 = analog, # 3 = up radiance, 4 = up irrad, 5 = quadratic, 6 = Old Satlantic cals # 7 = New Satlantic cals (b is multiplier) or MCP # Once a count is converted to a voltage, via fixed algorithm, # the voltage is converted to given units as follows: # Type 0: not converted or reported # Types 1 - 4: value = (volts - c) / b (a is unused) # Type 5: value = (a * volts^2) + (b * volts) + c # Type 6: value = a * (volts - c) / b # Type 7: value = a * b * (volts - c) # name: Name of channel # a: Calibration "a" value, unused for types 1-4 # b: Calibration "b" value # c: Calibration "c" value # cmin: unused # cmax: unused # units: Units that value decodes into 0 1 1 Ed412 0.0 -0.032154 0.000580 0 10 uwatts/cm2/nm 0 2 1 Ed443 0.0 -0.031644 0.000045 0 10 uwatts/cm2/nm 0 3 1 Ed490 0.0 -0.033918 0.000354 0 10 uwatts/cm2/nm 0 4 1 Ed510 0.0 -0.032167 0.000515 0 10 uwatts/cm2/nm 0 5 1 Ed555 0.0 -0.034141 0.000347 0 10 uwatts/cm2/nm 0 6 1 Ed665 0.0 -0.031322 0.000334 0 10 uwatts/cm2/nm 0 7 2 PAR 0.0 -14.5015 0.000944 0 10 uEinsteins/cm2/sec 0 8 2 Gnd 0.0 1.0 0.000496 0 10 volts 0 9 2 Diode 0.0 0.1 0.0 0 10 degC 0 10 2 DGnd 0.0 1.0 0.0 0 10 volts 0 11 2 Pitch 0.0 0.0430 2.6995 0 10 degrees 0 12 2 Roll 0.0 0.0427 2.6560 0 10 degrees
