+The table above lists the number of exposures (Nexp) in each of the filters available for the three MD fields for the period April-June 2009.  The column labeled Ncam lists the number of exposures processed at the camera stage (a small number failed on the chip analysis).  The column labeled Nstack lists the number of exposures nominally used for each stack.  Note that the exact number per stack depends on the skycell because of dithers and rotations.  The last column gives the maximum seeing accepted for each stack (in pixels).  Note that for MD06 and M08, since the y-band exposures all passed this limit, the actual max may be somewhat smaller than 5.0 pixels in these cases.

+For the IPP Team's reference, the scripts used to queue the data for the analysis stages can be found in ~ipp/stdscience/stdsci.v1.  For the chip analysis, there is as script for each field of with names like md06.v1.chip.  These scripts select the exposures for each of the nights in this period and set up the labels and the workdirs (along with other defaults).  The scripts used to launch the stack, diff, and magic runs have names like md08.v1.stk.  The 'mode' variable for each of these scripts must be set manually to one of 'stack', 'diff', or 'magic'.  For the moment, these scripts need to be run serially since they specify 'rerun' for the diff and magic stages.  Eventually, we should convince ourselves that difftool and magictool correctly generate only a single run for a given input set, in which case these could be run automatically.  
+
+The stacks are all build using a good seeing subset of the data from the entire 3 month period.  These selections were fairly subjective; in a future re-analysis pass, we can make a more educated choice for the inputs to maximize the S/N of the stack for point source detections (or other criterion as advised).  Each of the stacks has a label of the form MD0n.200906.v1.
