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.
