Parameters

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

Parameter	Mand	Type	Default	Constraints
srclisttable	yes	table	srclist.ds:SRCLIST
Name of the EPIC (combined) ML source list table
mfraclimit	no	real	0.75	$>0.$
Threshold value for MASKFRAC column. All sources with MASKFRAC$<$mfraclimit will have flag 1 set to T (see description).
brcolumn	no	string	RATE
Name of column to be used to define a circle of influence of a bright source (used to set flags 2 and 4)
op1	no	string	sqrt	sqrt|none
Operation to apply to 'brcolumn' to build the total expression to calculate the radius of the circle of influence to set flag 2 (and 4).
op2	no	string	mul	add|mul|none
Operation to apply to 'brfactor' to build the total expression to calculate the radius of the circle of influence to set flag 2 (and 4).
brfactor	no	real	100.	$>0.$
Number by which the 'brcolumn' is multiplied to obtain the 'circle of influence' radius in arcs (for flag 2)
minrad	no	real	10.	$>0.$
Minimum value (in arcs) of the 'circle of influence' of a source (for flag 2)
maxrad	no	real	400.	$>0.$
Maximum value (in arcs) of the 'circle of influence' of a source (for flag 2)
extfactor	no	real	1.	$>0.$
Number by which the column EXT is multiplied to obtain the 'circle of extended emission' radius in pixels (internally converted to arcs) (for flag 3 and 5)
extlimit	no	real	1.	$>0.$
Threshold value in pixels for a source to be considered extended.
maxextrad	no	real	200.	$>0.$
Maximum value (in arcs) of the 'circle of extended emission' of an extended source (for flag 3)
brlimit	no	real	10000.	$>0.$
Number of counts from SCTS for a point source to be considered causing spurious extended sources around it as set by flag 4
brexfraction	no	real	0.20	$>0.$
Likely spurious extended sources flagged with flag 5 should have less than this fraction of the brighter extended source brightness.
fixext	no	real	200.	$>0.$
Likely spurious extended sources flagged with flag 5 should be closer than this fixed distance to a brighter extended source.
detmlfraction	no	real	0.9	$>0.$
Likely spurious extended sources flagged with flag 6 should have (for just one of the 15 images) more than this fraction of the summed detection likelihood
badcolumn	no	string	CUTRAD
Name of column to be used to define the critical distance to a bad column in PN band 1 images (used to set flag 8)
badfactor	no	real	1.	$>0.$
Number by which the 'badcolumn' is multiplied to obtain the critical distance in image pixels (for flag 8)
pnclosetobadon	no	bool	no	yes|no
It switches flag 9 (close to bad column) on or off for PN
