Fix possible errors in the DPDD level 1 tables

      Description

      In going through at least the level 1 catalogs, I think there might be some errors or inconsistencies in the tables in the DPDD that are causing some confusion and can be clarified.

      • In DIAObject table, the description for fpFluxMeanErr is "Standard error of fpFlux" whereas psFluxMeanErr is "Standard error of psFluxMean". Is it standard error of *Flux or *FluxMean?
      • In SSObject table, for oeCov should the covariance matrix length 28 and not 21?
      • In DIASource table, should parentSourceId really be parentDiaSourceId and the description should refer to deblending from another diaSource, not Source?
      • In DIASource table, should the dipCov covariance matrix length be 21 instead of 15?

            In DIAObject table, the description for fpFluxMeanErr is "Standard error of fpFlux"
            whereas psFluxMeanErr is "Standard error of psFluxMean". Is it standard error of
            *Flux or *FluxMean?
            ZI: Good catch: it should read "Standard error of fpFluxMean"

            In SSObject table, for oeCov should the covariance matrix length 28 and not 21?
            ZI: Indeed, 28!

            In DIASource table, should parentSourceId really be parentDiaSourceId and the
            description should refer to deblending from another diaSource, not Source?
            ZI: yes, excellent catch!

            In DIASource table, should the dipCov covariance matrix length be 21 instead of 15?
            ZI: Indeed, 21!

            I have made these changes to DPDD and included them on my DM-7465 ticket branch.
