omdetect (omdetect-5.41) [xmmsas_20211130_0941-20.0.0]

Parameters

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

ParameterMand Type Default Constraints
setyesstringnone 
name of OM product FITS image file (either one produced by ommodmap or one produced by ommosaic).
 
outsetyesstringnone 
name of output OM source list file
 
wdxsetnostring“” 
name of OM priority-window data auxiliary file - needed for images produced by pre 5.4 sas
 
nsigmanoreal2.01.0–
number of $\sigma$ above background required for a detection
 
minsignificancenoreal1.00.0–
minimum significance of sources to be included in the SRCLIST table of the output source-list file. if 0 then no checking done.
 
levelimagenostringnone 
name of image of island detections
 
backgroundimagenostringnone 
name of background image file
 
regionfilenostring  
name of ds9 region file
 
detectextendednobooltrue 
Determines whether algorithm for detecting extended sources should be used
 
psfphotometryenablednoboolfalse 
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.
 
neighboursforpsfphotometrynointeger10-7
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.
 
psfphotometrysetnostring  
name of the output file for the source list with PSF-photometry
 
maxrawcountratenoreal1.00.0–
Maximum raw count-rate (as determined by aperture photometry) above which psf photometry should not be used.
 
backgroundmethodnointeger11-5
Determines which background method should be used- 1=current SAS method, 2=mean, 3=median, 4-mode, 5=using background image.
