INP=(IN1,IN2,...) where INn are file names of input pictures (up to ten) to be analyzed. A minimum of two is required.
OUT=(DC,SLOPE,YPOINT,DELTA) where DC, SLOPE, YPOINT, and DELTA represent output files names. DC is a required parmeter and is the dark current (or zero exposure intercept) picture. SLOPE is an optional file containing the slope picture. YPOINT is also an optional file containing the predicted Y value or what the DELTA file contains depending on if an X point is given. DELTA is an optional file containing the point deviating the most from the fitted line.
SIZE=(SL,SS,NL,NS) where SL, SS, NL, and NS are integer values specifying the starting line, starting sample, number of line, and number of sample respectively. The SIZE parameter has no real value for this program and may be omitted.
EXPO=(R1,R2,...) where Rn is a floating point number specifying the exposure for each of the input pictures. If the analyst is interested in only the dc picture or the relative slopes, the units of exposure are not important. There must be an equal number of values following EXPO as there are input pictures. There is no defaut. The exposure values must be in the same order as the input pictures.
The format is obtained from the input image label.
Valid:('NEGATIVE) is a keyword specifying that the negative of the dc picture is to be
outputted. The default is to output the positive picture.
MAXDN=I1 where I1 is an integer value specifying that the maximum DN in the output pictures is equal to I1. The default is 255 for byte and 32767 for halfword picture.
SCALE=R1 where R1 is a floating point number specifying that the second output (slope picture) is to be multiplied by R1. The default is 1.0.
X=R2 where R2 is a floating point number that is used to calculate the predicted Y value.
CONS=R3 where R3 is a floating point number that is used to calculate the point which diviates the most from the fitted line.
