# Calibration file for Satlantic Spectroradiometer OCR-100 # Serial 124 # Calibration date 25 Mar 2000 # Created by Brian Schlining, 28 Apr 2000 # # This is calibration file for one OCR-100 # Format of this file was chosen to be consistent with Satlantic 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 1 1 7 Lu412 1.748 -0.6484 0.00081 0 5 uwatts/cm2/nm/str 1 2 7 Lu443 1.742 -0.6504 0.00123 0 5 uwatts/cm2/nm/str 1 3 7 Lu490 1.736 -0.6602 0.00075 0 5 uwatts/cm2/nm/str 1 4 7 Lu510 1.733 -0.5298 0.00086 0 5 uwatts/cm2/nm/str 1 5 7 Lu555 1.729 -0.5755 0.00323 0 5 uwatts/cm2/nm/str 1 6 7 Lu670 1.721 -0.2440 0.00137 0 5 uwatts/cm2/nm/str 1 7 7 Lu683 1.720 -0.2489 0.00167 0 5 uwatts/cm2/nm/str 1 8 2 Gnd 0.0 1.0 0.0 0 5 volts
