Level 2 Help for TIMSPIX2

The user must provide the base name for the datasets used. For example,
to process "HAWAII32.PIX" and "HAWAII32.AUX" the name "HAWAII32" must be
given.  This procedure will then generate output datasets with the names
"HAWAII32.IRAD", "HAWAII32.DS1", "HAWAII32.DS3", "HAWAII32.DS5", 
"HAWAII32.RED", "HAWAII32.GRN", and/or "HAWAII32.BLU" as needed.

User's choice of a calibration option. The default
is to calibrate the data. When this option is in effect,
six band-sequential(BSQ) halfword-format files are
witten to disk. 

Optional specification of the subarea of the image that will
be used to calculate statistics for the fitting of halfword
data to byte data. The byte imagery thus created is input
to the D-stretch algorithm. The specification of this area 
is only required when the calibrated (CAL) mode is selected.
The default in CAL mode is to use the entire image to calculate
the statistics. 

Aspect (or horizontal to vertical) ratio used in the 
panorama correction (C130RECT). The default is 1.0,
which implies that the two dimensions are equal.
With ASPECT=1, the corrected TIMS image will have 
753 samples (or pixels) per line.

Optional subareas for the training of the D-STRETCH.
If subareas are specified, the data from these areas 
are used to calculate the correlation matrix. The default
is to use the entire image to calculate the correlation 
matrix.

Optional length for the stripping of the playback image. 
If no stripping is desired, the user should enter the number 
lines in the image for LENGTH. The default is to use a strip
length of 3500 lines to create the playback image.

TIMSCAL uses the date of data acquisition to determine the proper
calibration coefficients.  If defaulted, the date in the VICAR 
label is used. This parameter is needed only if the VICAR label
is incorrect, or if an abnormal calibration set is to be used.

Specifying the 'FLIP option will cause a left-to-right mirror
image to be generated.  This is necessary to get the proper
viewing geometry for TIMS data acquired in the Cessna aircraft.
