This is a wiki describing the false detection zoology tools/methods. This is NOT the page cataloging what we find.

Everything at the moment lives at /data/ipp009.0/heather. We can move this around or add to it.

Files in the directory (useful for creating region files, or further investigating interesting candidates)

• heather.blog.txt -- some of what I've done. Not complete.

• sas_skycells.sql
• sas_skycells.txt --these are list of sas footprints (filter, skycell, stack_id). Used by my perl scripts

• footprint-?-not-matched-psphot.fits -- these are the lists of false detections
• g.txt, r.txt, i.txt. z.txt, y.txt -- these are the lists of false detections in txt format (limited number of columns)

• make_region.pl -- perl script to make the region files. You may tweak this to get better (different) region files (example- changing the color or information displayed)
• grab_stacks.pl -- this just grabs the stacks and puts them in stack_id directories. Should only need to be run once.

• stack_id directories -- these contain the stacks (everything). Likely you will only need to look at the unconv.fits.
• *reg files -- these are the region files for ds9.

how to load up ds9 with regions

go to /data/ipp009.0/heather directory, then run something like this (choose the appropriate stack_id):

ds9 336341/RINGS.V3.skycell.1316.079.stk.336341.unconv.fits -region 336341.reg 

Note: to generate the commands interesting a filter:

/data/ipp009.0/schastel/sas_commands.sh <filter>

e.g.:

/data/ipp009.0/schastel/sas_commands.sh g

This probably loads too much information. You can turn off the text by going to Region -> Region Parameters -> Show Region Text

By default, I've just loaded the region files with the idet column (the object's ssn), to make it easier to investigate.

You can do screen grabs with gimp, or by zooming in and going to File -> Save Image.

Division of labor

we each should take a filter. Ken's priority is g and y, as those are the messiest. the reasons for false detections are likely filter dependent.

• heather : g
• serge :
• roy :

After those three, we can arm wrestle for what's left ;)
