meas_base uses a gen2/3 compatibility function from coadd_utils and also has runDataRef methods.
Remove gen2 from coadd_utils
Fix doc build for meas_base
Lauren MacArthur you seem to have worked with this code a bit so can you please take a look at the changes? I came to the conclusion that the reference subtask is not used any more and ci_hsc_gen3 seems to run fine without it.
I just left a bunch of comments on the meas_base PR. Did you want me to look at pipe_tasks too (I don't see a PR...)?
The pipe_tasks change is just a small removal of the usage of PerTractCcdDataIdContainer. Whether I merge it or not depends on whether Eli Rykoff merges DM-35670 first (which has the same fix in it).
Then I guess my work here is done! Pending successful Jenkins + ci_hsc + ci_imsim, good to go.
