Calibration Image Numbering Scheme

FUabcde.JuD

FU = Flight Unit (SU = Spare Unit will follow later)
a = code for temperature at which test was run

R = Room Temperature (20 deg C)
H = "Hot" Flight Temperature (-20 deg C)
M = "Middle" Flight Temperature (-30 deg C)
L = "Low" Flight Temperature (-40 deg C)

b = code for specific attribute being tested
D = Dark current
S = Shutter variability/stabillity
L = CCD linearity
W = Spectral calibration

X = Special test
c = code for spectral filter (see Table 1, below)
d = code for neutral density filter

0 = no filter
1 = 0.1
2 = 0.3
3 = 0.5
4 = 1.0
5 = 1.5
6 = 2.0
7 = 2.5

e = "run" number*
JuD = Julian Date of data acquisition

* This appears to be a sequential number that changes when none of the others change; however, sometimes the test conditions have changed and other times they have not. I am attempting to get clarification from Scott.
