• Jury duty Monday
• Spent a small amount of time on realtest.
• Did further study and preparation for starting DB replication.
• Got Josh's arclog.pl script running to collect Areca RAID card logs from nodes.
• Started parsing of logs to isolate read errors.
• RMA'd two boxes of WD drives.
• Started looking into buildtest and psLib TAP test failures.

• Dual convolution (branches/pap) + Merged into trunk (rr25999,26000) + Ran on 4 diffs from ThreePi_SouthernRegion with DUAL=T,

SPATIAL.ORDER=0. Some strange results for a small subset of skycells; otherwise good.

+ Some bad subtractions, clearly identifiable with chi² > 100! One

has 25453.6! Cannot fix merely by increasing ITER.

+ Softening errors produces nice behaviour --- fixed! + Some sources show up in the subtraction that should be masked ---

fixed.

+ Happy with dual convolution again, pending testing on a few

exposures.

• Stacking (branches/pap): investigating rejection behaviour + Completed rework of combinePixels + On each rejection pass, throw out only the most variant pixel;

change iterations parameter to iterations per input.

+ Happy with behaviour of stacking (r26011):

• 4 inputs from stack_id = 14006 (the Draper stack)
• stack_id = 25532 (full Draper stack from more recent warps)

+ Would benefit from threading the creation of the fake images

• Moved TEMP.DIR from ppStack recipe to site configuration; updated

production version
