     16 * DVO -> Mysql program written and working:
     17  * loops through all DVO sub-dirs, pulls in all measurement and average tables, joins and inserts into master dvoDetection table
     18  * problems with duplicates in DVO - ignoring for now, will investigate later
     19  * various system problems: broke ipp005 by building big database in the root partition
     20  * Moved to ippc00, after rsync-ing DVO Db, but too slow, so back to ipp005 - Gavin moved Dbs to partition with some space
     21  * completed ingest of 167 million detection rows in about 30 hours. Query speed increased from 40 minutes for a full frame to around 20 seconds.
     22
     23 * Testing of detection loading using new MySQL database:
     24  * path problems - csv dir not understood by ODM
     25  * DXLayer defaulting to 3PI rather than SCR
     26  * confusion over IMAGEID key: IMAGEID in smf files is not same as IMAGE_ID in DVO. Using SQL workaround.
     27  * crazy -999 "NULL" overflowing byte fields and breaking load
     28  * ImageMeta extension existing for empty Detection extension: fixed
     29  * duplicate detections in smf files breaking load: altered my tables to reject them and report to the log
     30  * nightly stacks in DVO do not have header values that were in original stack demo file. Changed code to query gpc1 for them instead
     31  * deep stacks not in addRun table (they were loaded manually) so I couldn't queue. Heather to the rescue...
     32  * found rows in StackApFlx and StackModelFit not in StackDetection: ignoring for now
     33
     34 * actual loading:
     35  * required lots of hand-holding over the weekend, but necessary to get everything loaded in time.
     36  * encountered bug causing program to halt with a 'database user' prompt. Spent a lot of time diagnosing issue, then fixing it (STILTS functions not closing all their database connections)
     37  * investigated high numbers of bad flux, duplicate objIDs. Confirmed same result with old code.
     38
     39 * made plot of magic mask fraction across lunations for Ken

    1541 * Spent many hours tracking down a memory corruption problem in addstar when importing SDSS data. It was very difficult to find since the problem only happened in an optimized build. Code was wiping out a saved variable on the stack.
