USAGE
uvotoptsum
imagefile=<filename>
maghistfile=<filename>
sumfile=<filename>
weightfile=<filename>
DESCRIPTION
This tool optimally coadds images.
PARAMETERS
- imagefile [filename]
- Name of file containing images to be optimally coadded.
This file will normally match sw*u.._sk.img.
- maghistfile [filename]
- Name of photometry FITS file created by uvotmaghist.
- sumfile [filename]
- Name of output sum file.
The special value NONE avoids creating this file.
- weightfile [filename]
- Name of output weight file.
The special value NONE avoids keeping this file.
- (alpha = -0.9) [real]
- Temporal decay index. The value -1 is not allowed.
- (exclude = DEFAULT) [string]
- The exclude parameter is passed to uvotimsum.
The exclude parameter determines which HDUs are included in the sum.
- (ignoreframetime = yes) [boolean]
- The ignoreframetime parameter is passed to uvotimsum.
The ignoreframetime parameter allows ignoring variation in frame time.
- (flexframetime = 0.02) [real]
- The flexframetime parameter is passed to uvotimsum.
The flexframetime parameter determines how much variation in frame time is allowed.
- (timezero = TRIGTIME) [string]
- The time relative to which the exponential decay is calculated.
The value can be a real number corresponding to mission elapsed time [s],
or it can be a keyword which will be taken from the primary HDU.
- (history = yes) [boolean]
- Write history keywords?
- (cleanup = yes) [boolean]
- Remove temporary files?
- (chatter = 1) [integer: 1-5]
- Standard HEAdas chatter parameter.
