 In order to understand the evolution of galaxies, detailed analysis of images plays a key role. During the last years telescopes working at different wavelengths have been imaging the whole sky. One example of this is the Sloan Digital Sky Survey. The generated images provides a wealth of information, publicly available, and hence allowing them to be used by any interested group in the study of their own samples of objects or generation of new samples. The two main processing of the ima...

Workflow Intialize Sample (2)

Thumb
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...

Workflow Detect ellipse failures and get votable wi... (1)

Thumb
It detects if ellipse has failed by checking if the resulting data file exists. It adds a column (validellipse) that contains 1 if ellipse didn't fail and 0 if ellipse failed. It returns a votable that contains all the data with the new column and a votable that contains only the rows where ellipse didn't failed. It uses astrotaverna plugin (http://wf4ever.github.com/astrotaverna/).
