LSST school workshop: Getting ready to do science with LSST data
Photometry extraction and validation using the HSC pipeline of HSC+u-band data in HSC-SSP deep fields (8947) - Mardi 13 juin 2017 16:00 - 16:40

Photometry extraction and validation using the HSC pipeline of HSC+u-band data in HSC-SSP deep fields

We obtained 300 hours at CFHT to conduct a u-band follow-up (CLAUDS program, u<27) of the HSC-SSP Deep fields (grizY, r<27), over 20 deg2. The u band is primarily used to find drop-out (high redshift) galaxies and compute photometric redshifts. Therefore it is necessary to combine the two datasets in a fully consistent way. To do this we developed tools to import the CFHT stack images into the HSC pipeline framework and ran the photometry extraction using the HSC pipeline tools. In this talk I will explain how we did it and I will show some validation results.
