VOIPortal Release

[Tushar Agrawal]

Dear All,

We are happy to announce the release of VOIPortal.

The current release of VOIPortal is a prototype version. It includes VOI Mosaic and PyMorph web applications. It also hosts few open social gadgets.

PyMorph Service allows users to derive morphological parameters for galaxy images. Users can provide the output FITS files generated by Mosaic Service as input. Service also provides the facility of uploading FITS files from individual machines.

PyMorph is a software pipeline which computes non-parametric and parametric morphological parameters of galaxies. PyMorph uses GALFIT (Peng et. al. 2002) for bulge disk decomposition of galaxy and SExtractor (Bertin et. al. 1996) for determining the initial values. PyMorph uses its own module to calculate Concentration index, Asymmetry, Clumpness, Gini Coefficient, second order moment of the brightest 20% pixels of galaxies (CASGM).

Mosaic service has also been updated to support HST UDF images.

Information about these web applications is available at:
