tem (STSDAS) synthetic photometry (synphot) software package. STSDAS is developed and maintained by the Science Software Group at STScI and is an external package layered on the Image Reduction and Analysis Facility (IRAF), which is developed and maintained by NOAO. Synphot is therefore portable to any host architecture supported by IRAF. IRAF/DAOPHOT users should consult A User’s Guide to Stellar Photometry With IRAF, by Phil Massey and Lindsey Davis. Detailed descriptions of the DAOPHOT photometry algorithms can be found in Stetson (, , ). ††Operated by the Association of Universities for Research in Astronomy, Inc. under cooperative. Phot is IRAF's basic photometry package. It can be loaded by entering digiphot and then apphot starting from the cl prompt. The phot task has five parameter lists with lots of variables, but IRAF will prompt you only for the critical ones. Entering epar phot will bring up the main parameter list. The important variables that you will need to.

A general overview and description of how to reduce CCD data. More specialized cookbooks exist for more specific areas (aperture photometry, spectroscopic data. web accessible tutorials, reference guides, and user manuals (see image reduction and photometry is worth the journey; as is the benefit. Appendix C lists other useful documentation available. 2 Photometry Methods. There are many techniques involved in doing aperture photometry, and these methods.
