Ajusting galaxy paramenters using sextractor (5)

• Download

This workflow creates configuration files for sextractor, it runs sextractor using this configuration files, it adds sextractor results to the input votable and adds new calculated columns. This task requires a votable as input, a template, a vocabulary and the specification of the column names that contain some required files (configuration files, image files, ...). These files must be accesible from taverna. Sextractor is called by an bash script as 'sex'. Every row in the votable cotains ...

Create votable from sextractor results (2)

• Download

The workflow creates a votable from the results provided by sextractor (votables). 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 sextractor and such files accesible from taverna. It uses astrotaverna plugin (http://wf4ever.github.com/astrotaverna/).

Run sextractor using a votable (2)

• Download

It runs sextractor and adjust the paramenters specified. This workflow has a dependency on the stil library (http://www.star.bris.ac.uk/~mbt/stil/). Sextractor is called by an bash script as 'sex'. Sextractor is called for every row in the votable. Columns where the configuration file and the image file name are defined must be especified. These files should be accesibles from taverna. ExperimentFolder provides the root folder for the experiment. If the configuration files contain refer...

• Download

This workflow uses astrotaverna artifacts. It creates files by using a template whose keys are replaced by data from a votable. A configuration file is created for every row in the votable. The keys must appear also in the vocabulary file and match column names in the votable. A column in the votable must contain the name of the result configuration file.

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.

Split VOTable into its values (1)

• Download

This workflow takes a single VOTable and splits it up in a vector for the names of fields, a vector for the UCDs of the fields, a vector for the UTypes of the fields, and a two dimensional vector for the values.

Associate SEP events at Earth with flare, ... (1)

• Download

This is the implementation of a use case worked on during CDAW3 of the HELIO project. SEP events propagated backward from Earth to the Sun. We allow for +- 30 min around the predicted time to search for flare events. The timing of the flare event informs the search time for Type III radio event (time_start to time_peak) and for the CME event (time_start to time_start+1h). Results are presented in a mulitlayered VOTable.
