 * Out Friday and most of Monday

 * Stacking (branches/pap)
  * Generating unconvolved mask and variance along with image
  * Investigating rejection behaviour: some stars rejected from all images, some features on a single image (e.g., burn) can result in pixels from all images being rejected, scattering of pixels rejected on a single image
  * Some stars not aligned: both warp and convolved warp centroid can differ by up to 1.5 pix
 * Dual convolution subtraction (also on branches/pap)
  * Can suppress common basis functions between dual kernels
  * Dual convolution looks better, but produces more sources from photometry
  * Variance map is lower for result of dual convolution
  * Investigated variance calculation, seems fine (and renormalisation should take care of it anyway), yet there are more pixels in the (S/N)^2^ image above threshold in the dual convolution diff compared to the single
  * Lots of sources at the edge of masked regions (where there's more noise in the smoothing) --> can be filtered with PSF_QF > ~0.7
  * Increased smoothing also brings out more nasty features (e.g., wiggles, burns)
  * Now satisfied that dual convolution is doing the right thing
 * Fixed temp directory for stacks --> /local/tmp --> /local/ipp/tmp
 * Translation program for Dave Monet (trunk)
  * Implemented translator (ppMonet) which now lives in a new directory (ppTranslate) with ppMops (trunk@r25923)
  * Added to publish system
  * Added 'active' flag to publishClient table
  * Sending lots of data (5811 exposures) from MD, 3pi, SVS, Sweetspot, STS, flatcorr
