| Abstract: |
Variable blurring of astronomical images by seeing and the instrumental Point
Spread Function (PSF) makes it challenging to obtain accurate photometric and
morphometric measurements under changing observing conditions. I show how the
new PSFEx PSF modeling software and the latest version of the
SExtractor source extraction tool can be combined to perform fully
automated, PSF-corrected source measurements. An
implementation of these techniques in the Dark Energy Survey Data Management
(DESDM) pipeline is presented. |
