This workflow join 14 votables, obtained from the workflow "Extract SDSS field information and PSF" in order to get a only one votable with all the information. Also it adds the columns "zp" and "magzeropoint" that are calculated from values provided in the inputs. The zp is -( aa + kk * airmass ) and the magzeropoint is zp + 2.5 * log10(53.907456)
