Workflows

Environment (2)

• Download

From a previously selected cube of galaxies residing in a remote database, we provide extragalactic environment parameters for all galaxies sample. This workflow takes as input the path of the tabular *.pckl Python pickle dataset created in the previous workflow, as well as the database connection settings and several criteria on how to filter the potential companions of the target galaxies. It provides a file with the SDSS identifiers of each target galaxy of the sample, environmental estim...

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...

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

• Download

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/).

Cocatenates several VOTables into one (3)

• Download

Snippet showing how to use AstroTaverna tool for concatenating several VOTables. The input is four VOTables with the same number of columns. The result if using sample values provided will be a four times vertically duplicated VOTable.

Create votable from different galfit param... (2)

• Download

The workflow creates a votable from the results provided by galfit. It returns this table and an aditional table that is joined to the input table. It requires a votable that contains a column with the file name resulting from running galfit and such files must be accesible from taverna. It uses astrotaverna plugin (http://wf4ever.github.com/astrotaverna/) and it has a dependency on stil library (http://www.star.bris.ac.uk/~mbt/stil/). The galfit files may come from adjusting 'disk, bulb, ba...

Calculate ellipses that describe a galaxy ... (2)

• Download

This workflow calculates the ellipses that better match a galaxy by doing two iterations. In the first one the center and the outer ellipse are aproximated because there might be bars that affect to the inner ellipses. In the second one, files with the ellipse data are built. It creates ellipse scripts using data from a votable, it runs ellipse, its results are added to the votable, it creates new scripts for ellipse using the previous results, it runs ellipse a second time and it finally in...

Create votable from ellipse results (2)

• Download

The workflow takes from a votable the names of files where the ellipse result is stored. These files contain data for several ellipses and the workflow takes the center from the inner ellipse and the ellipticitiy from one of the outter ones. It uses astrotaverna plugin (http://wf4ever.github.com/astrotaverna/).
