# Calibration file for PRR-600T2 Spectroradiometers Serial number 19615 # Model PRR-600T2 calibrated 31 July 2002 # File created 23 Aug 2002 by Daniel Cosgrove # # Format of this file was chosen to be consistent with Biospherical cal file # # First line has one entry for each address tag, specifying number of # channels for that address tag # # There follows 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 + (b * volts) + (c * volts^2) # 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, unused for type 6 # cmin: unused # cmax: unused # units: Units that value decodes into # 20 meter instrument, Serial 19615, Calibration date 7/31/2002 2 1 1 Ed412 0.0 -0.023644 0.000016 0 10 uwatts/cm2/nm 2 2 1 Ed443 0.0 -0.023892 0.000140 0 10 uwatts/cm2/nm 2 3 1 Ed490 0.0 -0.024214 -0.000245 0 10 uwatts/cm2/nm 2 4 1 Ed510 0.0 -0.024199 0.000020 0 10 uwatts/cm2/nm 2 5 1 Ed555 0.0 -0.021193 -0.000130 0 10 uwatts/cm2/nm 2 6 1 Ed665 0.0 -0.025464 -0.000013 0 10 uwatts/cm2/nm 2 7 1 PAR 0.0 -11.503801 -0.000858 0 10 uEinsteins/cm2/sec 2 8 1 Gnd 0.0 1.0 -0.000149 0 10 volts 2 9 2 Temp 0.0 0.1363 -0.0205 0 10 degC 2 10 5 Depth 0.6208 75.2424 16.9900 0 10 dbars # MCP-200's used to go in here; see example on 19607 2 11 2 Unused 0.0 1.0 0.0 0 10 volts 2 12 2 Fluor 0.0 1.0 0.0 0 10 volts 2 13 2 Gnd 0.0 1.0 0.0 0 10 volts 2 14 2 Gnd 0.0 1.0 0.0 0 10 volts 2 15 2 Unused 0.0 1.0 0.0 0 10 volts 2 16 2 Gnd 0.0 1.0 0.0 0 10 volts # 20 meter instrument, Serial 19615, Calibration date 8/14/2001 3 1 3 Lu412 1.0 -0.953636 0.000055 0 10 uwatts/cm2/nm/str 3 2 3 Lu443 1.0 -0.867697 0.000050 0 10 uwatts/cm2/nm/str 3 3 3 Lu490 1.0 -0.728088 -0.000360 0 10 uwatts/cm2/nm/str 3 4 3 Lu510 1.0 -1.211199 -0.000150 0 10 uwatts/cm2/nm/str 3 5 3 Lu555 1.0 -1.237655 -0.000294 0 10 uwatts/cm2/nm/str 3 6 3 Lu665 1.0 -2.631855 -0.000142 0 10 uwatts/cm2/nm/str 3 7 3 Lu683 1.0 -2.672493 -0.000020 0 10 uwatts/cm2/nm/str 3 8 1 Gnd 0.0 1.0 0.000124 0 10 volts
