     31 * Cluster cleanup: destreaked warps, diff convolved images
     32 * Added 3 kinds of exposure maps to ppStack (number, exposure time, weighted exposure time).  Set static BSCALE,BZERO so these are not too large.
     33 * Updated ppCoords so it can calculate cell coordinates in addition to chip coordinates
     34 * Set up system to collate microtest magic clusters in cell coordinates; published data to Camera group.
     35 * Investigating missing skycells in warp-warp diffs:
     36  * Found that warp-warp diffs don't always include all skycells available.
     37  * One possible cause is use of '-available' flag with difftool -definewarpwarp. Removed this flag: no longer necessary, and bad for current pipeline operating model.  Suspect another cause as well.
     38  * Almost all warp-warp diffs have been affected, at a typical level of 10% of skycells missing.  No, turns out this 10% are edge skycells, ignored due to constraints on good_frac.
     39  * Warp quality flags are all reasonable, and represent different stages of skycell overlap, from none to some with no sources, to some sources with no good PSF, to good.
     40  * Bad quality warps extend into the centre --- should have good PSF measurement there, but it's failing.
     41  * The SMF files are corrupted, with many extensions empty.  Dave Monet had told me about this, but I hadn't realised how extensive it is.  I have fixed psastro (was not checking return values) previously, so this should be a solved problem, but we're now dealing with its effects.  Hopefully, that means that the problem is not so extensive as we thought.
     42  * Sifting through SMF files to identify bad files.
