unfazed - Undo phase correction
This program will undo the phase correction part of the 
photometric normalization that was applied to Clementine 
UVVIS mosaics so that a new phase correction can be applied 
with "photomet".

This program is most appropriately applied to the special
"A" verion of the Clementine UVVIS data.  These data are
available online via ftp from pdsimage.wr.usgs.gov, and
can be found on /cdroms/CL_4XXXA for the appropriate quad
and location on the Moon.  The "A" data have had the
full photometric correction applied (with photom/photompr/moonpr),
but have not had the later empirical "fixes" applied to 
correct for the month1/month2 brightness differences (MONTH1_2,
NOTE: Old name was CLEMFIX) and the bug in the application of the
photometric correction (PHOTBUG, NOTE: Old name wasCLEMFIX2).
"unfazed" is applied to these data to avoid the need for undoing
these corrections.  The "A" data have the required phase-angle
backplane information for these calculations.

"unfazed" works on each band of an input cube to remove the 
phase function portion of the photometric correction and leave
the lambertian correction untouched.  Bands 1, 2, and (3,4,5)
in the UVVIS data each had different coefficients applied
to perform the phase function correction, so they must be
processed separately.  Information on the photometric correction 
applied to the Clementine UVVIS data can be found in the 
"volinfo" document on each cdrom and on the pdsimage.wr.usgs.gov 
site.

The result of running "unfazed" on "A" data should be
directly comparable to running "photom/photompr/moonpr"
(with the "noalbedo" option) to perform the lambertian
correction only.  The user can apply a new, user-defined
phase function correction using "photomet".

Parm	Description
FROM	Input cube file name. If the file extension is omitted, then ".cub" will be assumed.
SFROM	SFROM specifies the subcube using a single string for all three dimensions of the cube. The order of the three dimensions is always "samples:lines:bands". If a dimension is left blank, all the data for that dimension is selected. The default value of NULL for SFROM selects the entire cube. Any application below can be used for any dimension. To select specific data from any dimension: "10-100(3):11,12,15-20:1-10(2)" = This example will select every third sample starting with sample 10 thru 100. It selects lines 11 and 12, and 15-20. It selects every other band, starting with band 1 thru 10. There are special characters that can be used for selecting a subcube efficiently, such as "*","#", and "~". For examples type "help sfrom" in TAE. **NOTE** For more examples and explanation of the many features of the SFROM parameter, tutor the sfrom.pdf or refer to Introduction To ISIS, Section 6, of the ISIS User's Manual **
