April 6th, 2006 1:00 pm : ImageDetWG 'Phone Con
(Yes; this is an off week at Andy's request. I failed to send mail
last week postponing our meeting).
10am Pacific; 1pm Eastern
866 330 1200, passcode 300-2363#
Andy Becker will lead a discussion on the state of the art in Image
Subtraction. He has produced a couple of web-pages:
http://www.astro.washington.edu/becker/wcsremap.html
http://www.astro.washington.edu/becker/hotpants.html
that you might want to study in preparation.
Topics (to quote Andy):
* The method (Alard & Lupton)
* Weaknesses in the method
* Improvements on the original method implemented in hotpants (Noise
& masks)
* How to quantify results of differencing
* How the convolution affects photometry / astrometry
* Future plans (e.g slowly working on new code right now; do I want to
wrap this in the LSST schema?)
etc...
