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.

• 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

• 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)

Comparison and update values (1)

• Download

This workflow receives two files, the name of a table and the name of a field as input. One of the file should be contain a list of old values (name galaxy and value), and the other one should be a list of new values (name galaxy,value) The workflow makes a comparison between the two files. This comparison will be a list of 7 columns: name of the galaxy, old value, old error, new value, new error, difference of value, difference of error. In other hand, this workflow makes a sql script with ...

Gathering galaxy properties using HyperLEDA (2)

• Download

The user provides an ASCII text file with a list of galaxy names, and the workflow queries the HyperLEDA database and parses the response with the help of regular expressions included in simple Python scripts. The result of the workflow is a series of ASCII text files with the values of the equatorial coordinates in J2000 epoch, the velocities in km/s, the dust extinction coefficient Ag, the axis ratio of the isophote 25 mag/arcsec2 logr25 and the apparent total B magnitude BT. The performanc...

This workflow takes as input a file for each of this properties: J2000 Coordinates, velocity, galactic extinction, log of axis ratio, and the Total B-magnitude. With this properties it calculates the distance of the galaxy and, in other hand, the total apparent corrected B-magnitude. It takes account if the velocity of the galaxy is lower than a threshold (1000km/s), it can not be possible to calculate the distance so, in those cases the distance will be "NaN". At the end, it calculates the ...
