Photometry Assignment
The Big Picture
- Gather relevant and previously available photometry on NGC 281 (DONE, except Spitzer)
- Gather images from previous surveys (DONE)
- Herschel Images (DONE, but may be reprocessed)
- Aperture Photometry
- PSF photometry (Preliminary version, calibration missing).
- Check Aperture photometry for bad sources, missed sources.
- Create flags for all sources.
- Check Aperture vs. PSF photometry. Select one or the other for each protostar.
- Finalize Herschel photometry
- Merge all photometry.
