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

ParameterMand Type Default Constraints
outdirectorynostringcurrent directory 
Path/name of the output files directory
 
commentnostringUser comment 
User comment to output
 
filtersnoList of filters  
List of OM filters to be processed
 
exposuresnoList of exposures  
List of OM exposures to be processed
 
ommodmapnboxnointeger16 
ommodmap - Size of sliding box in units of 8 pixels
 
ommodmapnsignointeger3 
ommodmap - Significance level for sigma clipping
 
omdetectnsigmanofloat2.1.0:
omdetect - number of $\sigma$ above background mode required for a pixel to be regarded as being part of a source
 
omdetectdetectextendednobooleanT 
omdetect - Run the algorithm that looks for extended sources
 
omdetectminsignificancenofloat3.1.0:
omdetect- Minimum significance of a source to be included in the source-list file
 
usecatnobooleanT 
omatt - Use the USNO-SA 1 catalog for correcting the star positions
 
catfilenostringusno-catalogue fileusnocat.fits
Name of usno-catalogue fits file
 
omattrotateimagenobooleanT 
omatt - Create the rotated sky-image
 
omsrclistcombnsigmanofloat3.0 
omsrclistcomb- Used in source-matching number of $\sigma$ above which two sources are treated as different
 
omsrclistcombusecatnobooleanT 
omsrclistcomb - Use the USNO-SA 1 catalog for correcting the star positions
 
omsrclistcombalignaxesnobooleanT 
omsrclistcomb - If true (default) omsrclistcomb attempts to align all the images to a common RA/DEC origin.
 
maxradecerrnoreal1.0 
Maximum allowed RA/dec error in astrometry fit.
 
maxrmsresnoreal1.5 
Maximum allowed rms residual in astrometry fit.
 
processmosaicedimagesnobooleanF 
Process the mosaiced sky-images
 
ommergelistsregionfilenostring  
Region file name for ommergelists
 
ommergelistsplotfilenostring  
File name for ommergelists plot file
 
ommergeliststolerancenofloat2.1.0:10.0
Tolerance (arcsecs) used by ommergelists in source-matching
 
psfphotometryenablednobooleanF 
Allows using the PSF-photometry method by the task omdetect; If true then sources with close neighbours will have their photometry recomputed using point-spread-function fitting. Please note that in the current version of omdetect this method is under development ansd its use is currently disabled.
 
backgroundmethodnointeger11:7
Specifies the method for the point-source background determination by the omdetect task (related the PSF-photometry parameter).
 
maxrawcountratenofloat50.0.0:
A count-rate shreshold limiting the applicability of the PSF-photometry method in the task omdetect.
 
rawattitudenointeger10:2
Specifies the usage of attitude data by the task omprep: if set to 0, the attitude data is used according to the system variable SAS_ATTITUDe (either RAF or AHF); if set to 1, the raw attitude data (RAF) averaged over the first 20 seconds of exposure are used, if set to 2 then the raw atitude data are used averaged over the entire exposure.
