Summary

AstroGrid Science Workflows provide a ready-made series of complicated tasks linked together so that you only have to provide some simple constraints to obtain data. These values are entered in a very small web form. The underlying workflow is in the standard AstroGrid xml format which can, optionally, be saved and reloaded if you want to edit it or use it as a template. The data returned can be saved in MySpace or your desktop or sent to a suitable application for visualisation etc. depending on the nature of the data. You launch the workflows using the ParameterisedWorkflows menu on the Workbench. You will need an AstroGrid account (see Workbench Getting started) in order to save the workflow xml script or output to MySpace.

Available Parameterised Workflows

Click on each link for more details.

Solar Movie Maker

The Solar Movie Maker constructs a movie from SOHO EIT or TRACE images of the Sun. You select the start and end times and images.

Redshift Maker

The Redshift Maker finds multi-band images from the INT-WFS archive covering a given region and uses these to provide photometric redshifts for all suitable sources. You specify the region, and optionally, the method and storage location.

Colour Cutter

The ColourCutter selects IR (2MASS) and optical (SDSS, UNSNO-B or INT_WFS) data from a given region with chosen colours. You specify the region and the colour limits.

CTIP model

The Coupled Thermosphere Ionosphere Plasma Model generates ASCII files containing ionospheric parameter values. You select the date and the solar F10.7 flux.

SDSS DR4 Image Query

Returns SDSS DR4 SDSS images covering the region of sky you specify. (SDSS DR4 Homepage)

Cone Search

A short list of positions in a VOTable is sent as a series of cone searches to very large catalogues such as SDSS and 2MASS.
