Hi Kevin,
Sorry for not answering yesterday; I was out of the office...

Very good.

The input values range from 150 to 950, and the output values range from 255
to 76.

In McIDAS you list the content of stretch tables with the SU utility:
HELP SU
SU -- Image data stretching utility
SU INI name type unit <keywords>
SU MAKE name inlo inhi britlo brithi
SU LIST string
SU TABLE name
Parameters:
INI | initializes the stretch table defining the type of calibration,
calibration units and initial breakpoint settings; must be done
for making a new stretch table
MAKE | enters breakpoints in the table using brightness levels
LIST | lists the stretch tables saved on the workstation (def)
TABLE | lists the breakpoints stored in a stretch table
name | name of stretch table; 8 characters maximum
string | list only stretch tables beginning with this character string
type | calibration type for the input table (def=any calibration type);
to find the calibration type of an image, run IMGLIST FORM=ALL
and see the value for "type" in the output
unit | calibration units for the input table; valid units are RAW,
BRIT, RAD, TEMP, ALB or user-defined units; use command IMGPROBE
or D to list available units for an image (def=BRIT)
inlo | low value of the breakpoint for input values; specify in units
input with the 'unit' parameter
...
So, the listing was generated with:
SU TABLE CTP
