In that case, 1D-DRP refers to pfsConfig or operational database for the photometric information.</p> <p>Currently, "fiberMag" is allocated in pfsConfig and that may be useful to match with the spectroscopic data. On the other hands, the target selection is made using total magnitudes, so the total magnitude may be useful information. Also it may be useful to think about (for example) the aperture corrected spectroscopic data, and also any other purposes.</p> <p>We should keep talking about this further, but I'd like to file this ticket as a bookkeeping thing to add "totalMag" or "CModelMag" as well as "fiberMag" in pfsConfig. </p> DAMD-33 Do we need total mag as well as fiber mag?
