NAME
uvotaspcorr - find aspect corrections for UVOT sky images
USAGE
uvotaspcorr
input=<directory>
output=<directory>
DESCRIPTION
This tool processes an Swift observation attempting to find aspect corrections for UVOT sky images.
The aspect corrections can also be applied by setting apply=yes. Note that the input image files must be updatable (writable and uncompressed) to apply the corrections.
PARAMETERS
- input [directory]
- Swift observation directory. The structure of a Swift observation directory is
sw<obsid>/
auxil/sw*sat.fits
uvot/
image/sw*u*_sk.img
See also the flat parameter.
- output [directory]
- Name of output directory. This directory will hold the aspect solutions and log files. The sky images are modified in place.
- filter = ALL [string] (ALL|V|U|B|UVM2|UVW1|UVW2|WHITE)
- Which UVOT filter(s) to process.
- apply [boolean]
- Apply the aspect corrections? Note that the input images files must be updatable (writable and uncompressed) to apply the corrections.
- catspec = usnob1.spec [filename]
- Star catalog descriptor.
- (starid = NONE) [string]
- Star identification parameters.
- (flat = no) [boolean]
- Is directory hierarchy flat? Set flat=yes if all of the input files (attitude file, sky images) are in one (the input) directory.
- (chatter = 4) [integer] <1-5>
- Standard HEAdas chatter parameter.
