Pack Luminosity Profiles Research Object


Created: 2013-01-05 16:34:46 | Last updated: 2013-01-05 16:58:18

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 images ge...

Workflow Associate hessi flares with active regions (3)

Thumb
This workflow is querying the HFC ActiveRegions list and HEC hessi_flare list. It requires a time periode and a search radius arround the centre of an Active Region as inputs It produces two outputs: HFCout is a modified VOTable where a field is added with the number of associated hessi flares. combined_output is a 2 dimensional list with an VOTable for each Active region and one with an VOTable for all associated flares for that Active Region.

Thumb
This workflow takes a type of isnstrument as input and the minimum and maxium coordinates in HCI as input. Cadence for the location service is for defining the 'continues' presence. Output is a VOTable based on the ICS return where two columns are added for the time this instrument has entered and exited the Region of Interest.
