For the past week the IMC ODC has been reporting bad times (this problem started last tuesday) due to the WFS gain being lower than expected. You can see ODC plots on the LHO summary pages (https://ldas-jobs.ligo-wa.caltech.edu/~detchar/summary/) or more specifically at https://ldas-jobs.ligo-wa.caltech.edu/~detchar/summary/day/20140421/imc/odc/ H1:IMC-WFS_GAIN is set to 0.25, while the ODC is requiring == 1. Previously this gain had always been 0 (off) or 1 (on), so if a different value is going to be commonly used, we can adapt the ODC to match.
