Workflows

Executes Python script (4)

• Download

Snippet showing how to use Taverna Tool in Service template folder for executing a Python script. This workflow needs Python to be installed on the local system, and declared in the PATH enviromental variable, so any python script could be executed from a terminal.

Retrieve object properties from NED and VO... (4)

• Download

From an initial list of galaxy names, retrieve some of their properties from Virtual Observatory archives and services (NASA Extragalactic Database NED), and calculate others like Distance, based on the ones previously obtained (e.g. recession velocity, equatorial and galactic coordinates). The sample is filtered in a later step with criteria related to the angular size of the object and its declination. The goal is to build a sample of objects and their properties with up-to-date physical in...

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...

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.
