    v1 v2  
    22 * Better dark detrend spacing.  I don't think we're fully catching the time variations.
    33 * There seems to be a column style crosstalk between OTA01xy*2 and OTA21xy*2 and to a lesser extent to OTA11xy*2.  This appears to be reversable as well, with a bright star on OTA21 printing to the other OTAs.  OTA41 doesn't appear significantly affected.  I don't see a similar result on OTA67-OTA47, but that may just be missing a bright star in the sample I'm looking at.  Examples: o5677g0123o, o6042g0256.
     4 * There are issues with the fringe correction on a number of OTAs.  There seems to be a time based component to this as well, as 2015 data look reasonably good compared to older data (based on ippmonitor jpeg images).
