Caveats

The srcsize parameter value must be within a factor of 3 of the source size.  (03 Jun 2010)

Bugs

Only CIAO format regions are supported  (04 Feb 2011)

The tool will fail if there are any non-comment lines in the file other than the region definition: 

unix% cat flux.reg
# Region file format: DS9 version 4.1
# Filename: hrcf12810_000N001_repro_evt2.fits[EVENTS]
global color=green dashlist=8 3 width=1 font="helvetica 10 normal roman" 
source=1
physical
circle(16483.295,16325.297,24.139931) 

unix% srcextent
...
ValueError: substring not found

Workaround:

Comment out or delete the additional lines in the file: 

unix% cat flux.reg
# Region file format: DS9 version 4.1
# Filename: hrcf12810_000N001_repro_evt2.fits[EVENTS]
#global color=green dashlist=8 3 width=1 font="helvetica 10 normal roman" 
#source=1
#physical
circle(16483.295,16325.297,24.139931)

Tool does not add a history entry to the header.

The tool does not add a history entry to the output file header, which means the dmhistory tool cannot be used to recall the command.
