The 2014 Decam HiTS data we are currently using for ap_pipe and to evaluate the performance of the DCR model has worse seeing and not as even distribution of airmasses as the 2015 data. As a result, using the 2015 data as a template to run ap_pipe on the 2014 may work much better than using the 2014 data as a template for 2015, as we are currently doing. This ticket is to process the 2015 data through to generate DCR models, and run ap_pipe on the 2014 data twice, once using standard coadd templates and once using the DCR templates.
