The fibre fluxes are seeing-corrected, but not corrected to a large (ideally infinite) radius, so while they <b>might</b> provide acceptable colours they will not provide acceptable total photometry. Please add <tt>psfFlux</tt> measurements to the <tt>pfsDesign</tt> file.</p> DAMD-83

Consider use of PSF fluxes as well as fiber fluxes for spectrophotometry

We will 'apply' the Galactic extinction in the flux calibration (we infer the intrinsic spectral shape of a specphot std from the stellar typing using photometry and absorption lines, and then apply the Galactic extinction to it to make the 'expected' spectrum that we observe).  I wonder if it would be useful to have a fiducial E(B-V) in pfsDesign...?  There is a few Galactic extinction maps in the market and I do not know which one is most popular these days.</p> <p>As agreed in the 2D DRP technical telecon 2020-10-26, addressing <a href="https://pfspipe.ipmu.jp/jira/browse/DAMD-33" title="Do we need total mag as well as fiber mag?" class="issue-link" data-issue-key="DAMD-33"><del>DAMD-33</del></a> (introduce totalFlux) and <a href="https://pfspipe.ipmu.jp/jira/browse/DAMD-84" title="Add photometric errors to the pfsDesign and pfsObject files" class="issue-link" data-issue-key="DAMD-84"><del>DAMD-84</del></a> (add photometric errors) in this same ticket.</p> <p>Merged to master.</p> Relates DAMD-84 DAMD-33 Development Rank 0|02qprn:o Reviewers price Sprint 2DDRP-2021 A Story Points 2.0
