srcdisplay (srcdisplay-1.20) [xmmsas_20211130_0941-20.0.0]

Examples

To overlay the sourcelist srclist.ds generated previously by eboxdetect on an image image.ds the following command can be used:

srcdisplay imageset=image.ds boxlistset=srclist.ds

This would overlay circles, each of radius 5 pixels, around each source detected by eboxdetect. To overlay circles of radius 0.01 degrees, use the following:

srcdisplay imageset=image.ds boxlistset=srclist.ds sourceradius=0.01

To perform the same as above, but also write out a DS9 region file named regions.txt, detailing the source regions corresponding to the displayed circles,the following command could be used:

srcdisplay imageset=image.ds boxlistset=srclist.ds sourceradius=0.01 withregionfile=true regionfile=regions.txt

To use a source radius determined from the RADEC_ERR, position error, column in the sourcelist use:

srcdisplay imageset=image.ds boxlistset=srclist.ds useposerr=yes

To use a source radius determined from a position error column with a user supplied name:

srcdisplay imageset=image.ds boxlistset=srclist.ds useposerr=yes poserrcol="POSERR"

NB: The errors are assumed to be in units of arcseconds and the column must be of type REAL*32.

To add a systematic error of 2 arcseconds to the position error, use:

srcdisplay imageset=image.ds boxlistset=srclist.ds useposerr=yes syserr=2.0
