Querying SDSS DR8 to get magnitude properties (2)

• Download

This workflow gets a VOTable with the RA and DEC among others values of a list of galaxies. The workflow queries the SDSS DR8 VO conesearch service, to extract the objID, specObjID, ra, dec, u, g, r, i, z.

Searching for near galaxies in NED service (2)

• Download

This workflow needs as input an ascii table with a list of galaxies. This table contains the PGC name of the galaxy, the CIG number, the radius of searching, Z1 and Z2. The workflow uses the radius, Z1, Z2 and the PGC name of the galaxy to query NED service and get the html with the list of companions. This html is parsed and it is built a VOTable with the RA, DEC, Magnitud, Redshift, Separation, Velocity of each companion.

Joining VOtables with information to execu... (3)

• Download

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)

• Download

This workflow joins two main nested workflows: - "Extract SDSS field information and PSF" workflow, which gathers information from SDSS VO service and from the header image in several VOtable. It also generates the psf files. - "Joining VOtables with information to execute Sextractor, Galfit and Ellipse" workflow, which joins the VOtables generated by the previous workflow to get only one VOtable with all the information

Extract SDSS field information and PSF (5)

• Download

This workflow gathers information needed by the execution of Sextractor, Galfit and Ellipse, from the SDSS VO service. It receives two inputs: 1) An ascii table with information about the image such as data of the field, name of the fits file or if it is barred or not. 2) A configuration file with the paths where the files needed by the workflow can be found and other paths where to store the files generated by the workflow This workflow extracts the band from the image header, and the info...
