# v2: for ktofr9
# v3: exclude from presccdglob CCD where bg/bgOB_ccdCCDr_en.fits doesn't exist
# v4: * only return presccd, not presccdglob
# * remove the making of reg/obOBccdN.reg, since it is now made in whichccd2
# v4simple: * use simple regions simplechipsregOB.reg
# * make reg/obsimple*.reg
# v4simple2: * make the _xfov_ptsrc.reg files even for OBSIDS in badskyfovob
# PURPOSE: this function returns the ccd's that are present for this shell,
# PURPOSE: and makes ccd regions AND shell regions
# INPUT: rlo, rhi in pixels
# OUTPUT: * return value: a string with the CCD's which have counts in the provided
# range [rlo,rhi]
# OUTPUT: * prefix+'xfov_pt_simple.reg'
