Retrieving information from HST ConeSearch... (1)

• Download

This workflow retieves information from Hubble Space Telescope VO Services in the form of VOTables. The input of the workflow is an ASCII file with a list of source names. This file is converted to a VOTable, and coordinates added with an extra-column needed to query SIAP Image service. The final result are two different VOTables issued as the response of both VO Services, Images VOTable has been previously filtered.

Discovery of Brown Dwarfs mining the 2MASS... (1)

• Download

Brown dwarfs are objects occupying the gap between the least massive stars and the most massive planets. They are intrinsically faint objects so their detection is not straighforward and, in fact, was almost impossible until the advent of global surveys at deep optical and near-infrared bands like SDSS, 2MASS or DENIS among others. Here we propose to mine the SDSS and 2MASS databases to identify T-type brown dwarfs through an appropriate combination of colours in the optical and the infra-red...

Intialize Sample (2)

• Download

This workflow saves a tabular *.pckl Python pickle dataset in the local file system, containing values calculated on physical parameters associated to potential companions of a sample of target galaxies. These original physical parameters are extracted from a postgreSQL database, containing information of all galaxies covered by the SDSS spectroscopic survey. The workflow first access the external database located in the AMIGA server and selects the target galaxies from the sample (those havi...

VOTable of NED Images from a List of Objects (1)

• Download

Extraction of metadata using NED Image Virtual Observatory Service into a single VOTable, providing a list of objects and the width for each field in arcmin. Among the most relevant metadata are the URL link to the FITS images. This Wf makes use of a Tool developed as an internal pyhton script file.
