Need Input from the MSSL Community

MSSL Astrogrid developers (KevinBenson and ElizabethAuden) are looking for scientific applications commonly used by MSSL solar and astro people. We are quite interested in placing those applications and services on the grid to be accessible through Astrogrid and other Virtual Observatories. What non-interactive() applications and services(*) do you run when analysing data?

Here are some examples of applications that could be deployed as Astrogrid services:

  • SolarSoft procedures(*)
  • galactic models
  • emldetect or omdetect

If you are interested in deploying an application you use as an AstroGrid tool, please email Kevin at kmb@mssl.ucl.ac.uk or click KevinBenson. Also, feel free to register on the wiki and add your suggestions at the bottom of this page. Include the following information about your application:

  • Application name
  • URL or small description that explains what the application does
  • Syntax for calling the application and a list of inputs / outputs

There are currently three AstroGrid tools running at MSSL.

  • First, the Solar Movie Maker uses SolarSoft routines to reduce TRACE, SOHO-EIT and SOHO-CDS data into calibrated images. MPEG movies are generated from these images using the Berkely MPEG encoder.
  • Second, the Solar Overlay tool also reduces TRACE, EIT and CDS data, but it also overlays images from all three instruments that fit into the same time window.
  • Third, the Generic Movie Maker uses the Berkeley MPEG encoder to generate MPEGs of any JPEG, GIF, PPM, or FITS image.

There are also AstroGrid data sources that are available through MSSL such as

  • SEC - Solar Event Catalogue from EGSO
  • SOHO-CDS fits files
  • SOHO-EIT fits files (from VSO)
  • Yohkoh fits files from MSSL
  • small subset of TRACE fits files

In some cases, the actual data files are held elsewhere, but the header information can be queried through a database at MSSL. Querying these sources returns files along with tabular data in a VOTable format. If you know of other data archives that will provide a link to individual fits files through a URL, list them below or email Kevin. Information about these datasets will be added to the query tool.

Coming soon before the September workshop:

  • EGSO Query Web Services
  • MSSL GOES fits data
  • Solar derotation tool (using Dominic Zarro's SolarSoft routines)

* Non-interactive means that you input files or variables, and then the program gives you files or variables as output. When the application or service is finished, it doesn't ask you questions or require mouse clicks.

** Services can be web services or actually http type services where by you input everything in a url and the output comes back via that url.

* Any non-GUI IDL application can be deployed as an Astrogrid tool. In fact, the Solar Movie Maker and Solar Overlay tools running at MSSL are IDL applications.
