      Description

      The EPO team would like several hundred Type Ia Supernovae with time-series imaging, light curves, and derived light-curve parameters to use in a project on SNIa Cosmology.

          My first suggestion was to use the Supernova Legacy Survey data, since the light curves (and their derived parameters) have been published, and all individual images are available through the Canadian Astronomical Data Center.
          The challenges are that the single MegaCam images are large and come in MEF format, and it seems that a non-trivial amount of processing (swarp/mosaic, creating single-night stacks) would be necessary in order to assemble a data set for a suitable amount of SNeIa (hundred or more), since most SNLS SNeIa are faint (it was a deep survey). 
          EPO is going to look into using ZTF data instead, but the limited redshift extend might not be suitable for their cosmology-oriented project.

          Helped a bit with this by identifying useful data from precursor surveys available through the CADC which could be used by EPO for their supernova activity.

          S19 contributions done.
