Chapter 1. Introduction MOPEX User’s Guide MOPEX (MOsaicking and Point Source Extraction) is a package developed at the Spitzer Science Center for astronomical image processing. MOPEX requires input images in FITS format. As an example, if the user has basic calibrated FITS images from the Spitzer Space Telescope archive, MOPEX can be used to level the backgrounds of the input images, co-add them together to produce a mosaic with optional rejection of outliers (e.g. cosmic rays), and perform point source extraction and/or aperture photometry on the detected sources. MOPEX can be run in two ways - either from the command line, or using the Graphical User Interface (GUI). The GUI is more user-friendly, especially for first-time users, but the command line contains some additional functionality that has not yet been implemented in the GUI. MOPEX is available for Mac, Linux and Solaris (see the MOPEX Download page for specific availability). ***NEW (November 2010)*** Appendix C gives the current best correction factors for PSFfitted fluxes for all Spitzer instruments. ***NEW (March 2012)*** Appendix D gives some tips for Spitzer data. 1.1 Important Documentation The following documents and webpages are recommended reading, and are referred to throughout this User’s Guide: • Spitzer Data Analysis Cookbook: http://irsa.ipac.caltech.edu/data/SPITZER/docs/dataanalysistools/cookbook/ • IRAC Instrument Handbook: http://irsa.ipac.caltech.edu/data/SPITZER/docs/irac/iracinstrumenthandbook/ • MIPS Instrument Handbook: http://irsa.ipac.caltech.edu/data/SPITZER/docs/mips/mipsinstrumenthandbook/ • IRS Instrument Handbook: http://irsa.ipac.caltech.edu/data/SPITZER/docs/irs/irsinstrumenthandbook/ • MOPEX main page: http://irsa.ipac.caltech.edu/data/SPITZER/docs/dataanalysistools/tools/mopex/ • MOPEX download page: Introduction Important Documentation
