-This week, we have been running some more example processing (MD08 stacks and SweetSpot), while also tracking down various bugs and trying to finish off some additional development tasks.  Paul has been making good progress on stacks and diffs.  On diffs, he has made a first pass at a completely working dual convolution implementation.  This week we will run some large-scale data sets (MD and/or ThreePi) with this as the main difference algorithm to compare with earlier analysis runs.  Chris has been concentrating on y-band fringes and verifying the flat-fields.  The y-band fringe analysis issues turned out to be harder to track down than expected, but in the end he has gotten the code to work quite well.  There were a number of bugs related to things like video cells and the pattern noise removal which took some hunting.  We have run a good-size y-band test over the weekend that we can use to check the impact on magic.

 I adjusted the photometry zero-point analysis code so that it can (a) use the entire exposure for the zero point calculation (this is now the default) and (b) measure the 'blue edge' of the mag_obs - mag_ref distribution, in the theory that this is representative of the disk population, and a bit less sensitive to the changes in population sample.  The test I ran showed that I got the code backwards, so I need to fix that and also implement the bootstrap-resampling analysis of the error as suggested by Shaun Cole.  I have also been digging into some of the photometry issues in the difference image analysis, but have not yet gotten very far on that.  The MOPS team has reported inconsistencies between the magnitude and error distributions in detections from the difference images.  Joel has also noted a problem with the forced photometry analysis which is potentially related.
