NAME
uvotlss - calculate large scale sensitivity corrections
USAGE
uvotlss infile=<filename> lssfile=<filename>
x=<float> y=<float> input=<string>
history=<boolean> chatter=<integer>
DESCRIPTION
This tool calculates the large scale sensitivity correction (LSS) factor
for a position, or updates and applies the LSS correction factors in
a table created by uvotsource.
PARAMETERS
- lssfile [filename]
- Name of large scale sensitivity file or CALDB.
- input [TABLE|RADEC|IMAGE|DET|MM]
- Input mode. This determines how the infile, x, and y parameters are processed.
- infile [filename]
- If input=TABLE, infile must give a FITS table created by uvotsource with DETX, DETY, AP_COI_SRC_RATE, AP_COI_SRC_RATE_ERR columns. If input=RADEC or input=IMAGE, infile must give a FITS sky image which contains WCS keywords for the sky coordinates and WCS D keywords for detector coordinates.
If lssfile=CALDB, infile is used to parameterize the CALDB lookup.
- x [real]
- This gives the X coordinate for the input mode.
If input=RADEC, x is the source R.A. [deg].
If input=IMAGE, x is the X FITS coordinate in the infile sky image [pixel].
If input=MM, x is the X coordinate in the UVOT TELDEF DET system [mm].
If input=DET, x is the X coordinate in the UVOT TELDEF DET system [pixel].
- y [real]
- This gives the Y coordinate for the input mode.
See the x parameter for a description of the coordinate system and units for
each value of the input parameter.
- (history = yes) [boolean]
- Write parameter history? The parameter history is only written for input=TABLE.
- (chatter = 1) [enumerated integer]
- Standard HEAdas chatter parameter.
EXAMPLES
1. This example illustrates running uvotlss specifying the table
extension to process:
uvotlss input=TABLE infile=table.fits[2]
2. This example provides a sky image and specifies the source sky position on the command line:
uvotlss input=RADEC infile=sky.fits[vv123091236I] x=243.435 y=-23.54
