This branch of the repository contains the Planck Simulation Package. It is subdivided into the following main sub-packages: - libcfitsio: external library required for FITS file access (see http://heasarc.gsfc.nasa.gov/docs/software/fitsio/) - c_utils, libfftpack and libsharp: C libraries required by other LevelS components - cxxsupport: miscellaneous C++ utility functions needed by the C++ codes - Healpix_cxx: software package implementing the Hierarchical Equal-Area equi-Lateral Pixelisation scheme - skymixer2: extrapolation and combination of foreground components - cxxmod: C++ modules simulating various effects needed by multimod - pntsrcconvolver: C++ point source convolution code, used by multimod - multimod: C++ code for production of Planck data time streams - cxxtools: package containing several convenient standalone modules - portability: non-standard extensions needed by Fortran codes - Modules: common Fortran modules used by more than one of the simulation packages - CAMB: code for computing CMB power spectra Main author: Antony Lewis (antony <at> cosmologist <dot> info) - Beam: Codes for creation and manipulation of beam patterns Main author: Mark Ashdown (maja1 <at> mrao.cam<dot>ac.uk) - simmission3/4: Code for simulating the satellite dynamics Main author: Daniel Mortlock (d _dot_ mortlock<at>imperial.ac.uk) - zlelib: library for computing zodiacal light emission Main author: Michele Maris (maris(at)oats.inaf(dot)it) - LFI-specific: Code used by the Low-Frequency Instrument only Main author: Davide Maino (davide(dot)maino_at_mi.infn.it) - conviqt: latest incarnation of the total convolution algorithm Main author: Gary Prezeau (Gary.Prezeau_at_jpl.nasa.gov) In addition: - SetupSimulation allows to choose simulation parameters. Finally, the directory "etc" contains template and default parameter files.
