Merge a HiRISE channel pair to make a single image
Overview
Parameters
Example 1
Description
The program allows the user to combine two HiRISE channels to form a
single CCD image. Histitch will typically be run after radiometric
correction and prior to geometric processing. The two input files
must be the individual channel files (channels 0 and 1) of the
same CCD observation. The program will test to make sure the
Observation IDs and CCD IDs of the input cubes match, and that one
cube is channel 0 and the other is channel 1. The program is clever enough
to figure out the channels associated with each input file and correctly
order them in the output file. Any ancillary data "blobs"
will not be propagated to the output file. The channel number on
the output cube is set to 2 to signify that it is the combination of channels
0 and 1.
histitch can create a CCD image if when only one channel is provided.
The proper placement, left half of CCD for channel 1 images, right half for
channel 0, is determined from the input file and the remainder of the CCD
is filled with Nulls.
This is the first of a pair of input HiRISE channel
image files. This file can be either the channel 0
or 1 file. The pair of input files must correspond
to the the same observation of a HiRISE CCD.
This is the second of a pair of input HiRISE channel
image files. This file can be either the channel 0
or 1 file. The pair of input files must correspond
to the the same observation of a HiRISE CCD.
If the user does not provide a file for the second file, histitch
will create a full CCD and map the FROM1 file into the proper
location in the CCD. This allows creation of the full CCD without
both channels being required.
