Online Astro-Photometry tool

Checking...

This tool is for Photometry of Astronomical images, to have quick and easy estimate of stellar magnitudes.
Using the tools is as simple as just to provide the Image file and RA-Dec of the desired source. That's all, you get the calibrated magnitude.
Supported formats are only .FITS and .FZ files. The .FZ is for compressed file from Heasarc's FPACK utility.
RA-Dec pair should be in sexagesimal fomat, where RA in hours and Dec in degrees.
Optional paramters are available to tune photometry parameters. For most cases default parameters are good enough.
Can do both aperture and PSF photometry. However, PSF photometry is in beta phase.
