# satlan.readme
#
# This is the format for a 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

Satlantic configuration files follow this naming scheme: 
satlan.[3-digit serial number].[channel].[date of calibration]

If the satlantic uses channels 1-8, it is channel 'a'.
If it uses channels 9-16, it is channel 'b'.

For example: satlatic #012 calibrated on 07 April 1998 using channels 1-8 (instead of 9-16)would be named:
satlan.012.a.19980407
