Import PDS formatted Dawn FC EDR or RDR image cube into Isis format cube
Description
This application will import a PDS formatted Dawn Framing Camera (FC) level
1 (EDR) or level 2 (RDR) radiometrically calibrated image into an Isis cube.
The resulting cube ("TO" parameter) will function properly in other ISIS
cartographic software such as "spiceinit" and "cam2map". The Dawn FC EDRs
and RDRs will be available for download from the PDS Small Bodies Node at
http://pdssbn.astro.umd.edu/.
Although allowed in PDS standards, Dawn EDR and RDR files are arranged in a
rarely used spatial storage order. That is, the bottom line of the image
is stored first within the image array object contained in the PDS file.
This
application modifies the arrangement by reversing the line storage order in
the output cube; however, be aware that other
non-ISIS software may not apply the reversal.
Therefore a Dawn image may appear to be flipped from top-to-bottom when
comparing to ISIS cubes.
Please note that ancillary Dawn PDS products such as mosaics or other map
projected RDRs should not be used as input to this program. Instead use the
general "pds2isis" program.

Removed tests on HorizontalPixelScale and VerticalPixelScale; Added
optional TARGET parameter to allow TargetName specification.

| Jeff Anderson | 2011-07-26 |
Changed the program to write the NaifFrameCode in the labels to include
the filter number. This was done because the Dawn FC team provided a new
instrument kernel (IK) with band dependent focal lengths and optical
distortion parameters. The camera model then uses this update label
keyword to read the correct camera parameters.

FROM
Description
Use this parameter to select an existing Dawn EDR or RDR filename.
This file must contain the PDS labels. The program will apply a
sanity check to make sure the labels match the expected Dawn PDS
format and report a user error if they are unacceptable.

Parameters:
TARGET
Description
In order for ISIS cartographic applications to properly function
a TARGET_NAME keyword and value must be present in the source PDS
labels. During the cruise phase of the Dawn mission, preliminary
versions of the Dawn PDS EDRs and RDRs at times did not contain
the TARGET_NAME or it was left blank. This parameter allows the
user to correct that oversight by providing "MARS" or "VESTA" as
the parameter value. Also, star observations were made and
recorded in the TARGET_NAME. The various star names are not
recognized by ISIS and this application will produce an unknown
target error message. If you plan to use some of the ISIS sky
projection programs such as "skymap" or "skypt" you can set the
this parameter to "SKY".
If this parameter is not provided it will use the value in the
PDS labels given by TARGET_NAME.
