This workflow join 13 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", "magzeropoint", xconvsize, yconvsize that are calculated from values provided in the inputs. The zp is -( aa + kk * airmass ), the magzeropoint is zp + 2.5 * log10(53.907456), the xconvsize is roundUp(nx/10) and the yconvsize is
roundUp(ny/10)

- cat: File path where sextractor results is allocated.
- sex: File path where the sextractor config file is allocated (one for each galaxy).
- sexparam: File path for general sextractor configuration file (the same for all the galaxies)
- checkimage_name: File path where the sextractor image result is allocated
- galfit: File path where the input for the first galfit execution is allocated.
- galfit_exp: File path where the output for the first galfit execution is allocated.
- galfit2nd: File path where the input for the second galfit execution is allocated.
- galfitgal: File path where the output for the second galfit execution is allocated.
- model: File path where the galfit image result is allocated.
- ellip_tab: File path where the output for the first ellipse execution is allocated.
- ellip_resultheader: File path that contains the column descriptions for the ellipse results (first iteration).
- ellip_resultdata: File path that contains an ascii table with the ellipse results (first iteration).
- ellip_tab2: File path where the output for the second ellipse execution is allocated.
- ellip_resultheader2: File path that contains the column descriptions for the ellipse results (second iteration).
