Might you have a moment to give this a quick look? I've fixed the butler issue you also came across for the comparison scripts and also made a number of other updates. All scripts seem to be in working order. You can have a look at the current status of the plots on tiger at Princeton at /tigress/HSC/HSC/rerun/lauren/LSST/working/cosmos/plots/. Note that for the "comparison" plots, I'm actually comparing the same run against itself (I didn't have two different recent runs handy, but I will do further testing on Hsin-Fang's weekly processing soon). Of interest though is for the visitComparison I applied the meas_mosaic results to only one, so these plots in particular show the uberCal correction fields on a per object basis for the mag and astrom comparisons, e.g.:
/tigress/HSC/HSC/rerun/lauren/LSST/working/cosmos/plots/HSC-I/tract-9813/visit-1228/compareVisit-v1228-diff_base_GaussianFlux-sky-gals.png

Review completed on GitHub.

This needs a bit of cleanup before merging. In particular, some commits should be orthogonalised and there are a few features and refactorings I believe you should think about.

Paul Price, I realize you marked this as reviewed, but your comments led to some significant changes and there were a few I pushed back on (see comments on the PR in github). Accordingly, I want to give you another chance to have a look at my changes and comments before I merge. Thanks again for such a thorough review.

No need. (:
