Parameters

This section documents the parameters recognized by this task (if any).

Parameter	Mand	Type	Default	Constraints
set	yes	string	none
name of OM product FITS image file (either one produced by ommodmap or one produced by ommosaic).
outset	yes	string	none
name of output OM source list file
wdxset	no	string	“”
name of OM priority-window data auxiliary file - needed for images produced by pre 5.4 sas
nsigma	no	real	2.0	1.0–
number of $\sigma$ above background required for a detection
minsignificance	no	real	1.0	0.0–
minimum significance of sources to be included in the SRCLIST table of the output source-list file. if 0 then no checking done.
levelimage	no	string	none
name of image of island detections
backgroundimage	no	string	none
name of background image file
regionfile	no	string
name of ds9 region file
detectextended	no	bool	true
Determines whether algorithm for detecting extended sources should be used
psfphotometryenabled	no	bool	false
If set to true the photometry for FAST mode images will be performed using psf fitting, and for IMAGING mode for those sources with close neighbours. In the current version of the task the use of this parameter is disabled.
neighboursforpsfphotometry	no	integer	1	0-7
Determines the minimal number of neighbours of a source to implement its PSF-photometry (in the case of the parameter psfphotometryenabled set to true). To save computing time, PSF-photometry is not applied to the sources having the number of close neighbours less than neighboursforpsfphotometry.
psfphotometryset	no	string
name of the output file for the source list with PSF-photometry
maxrawcountrate	no	real	1.0	0.0–
Maximum raw count-rate (as determined by aperture photometry) above which psf photometry should not be used.
backgroundmethod	no	integer	1	1-5
Determines which background method should be used- 1=current SAS method, 2=mean, 3=median, 4-mode, 5=using background image.
