This software is made available under the terms of the GNU GPL licence that comes together with this package. It consists of a collection of IDL and Fortran 90 subroutines. (1) F90 Compilation -------------------- Two options are available: (1.1) - Define the environment variable $FCFLAGS as the directory where fftw3.f lies e.g. setenv FCFLAGS "-I/usr/local/include" - then run : ./configure --prefix=$HOME --with-healpix=$HEALPIX make make install make clean (1.2) - Edit your own Makefile. A few examples are provided in /F90: Poker/F90/Makefile Poker/F90/Makefile.example Poker/F90/Makefile.franklin Poker/F90/myoldMakefile Poker/F90/Makefile.inf-calcul1 (2) IDL setup: -------------- - Insert the following lines in your $IDL_STARTUP: defsysv, "!fwhm2sigma", 1.0d0/sqrt(8.0d0*alog(2.0d0)) defsysv, "!arcmin2rad", 1.0d0/60.0d0*!dtor defsysv, "!undef", -32768 defsysv, "!poker", getenv("POKER_DIR") ; this should point to the Poker directory that you get when you untar Poker.tar.gz defsysv, '!arch', "whatever" ; if set to "parallel", the it will pause to let you launch poker_mbb separately defsysv, '!ordi', 'whatever' !path = !path + ':' + expand_path("+"+!poker+"/IDL") (3) Test: --------- - /IDL/poker_example.pro guides the user through the estimation of the power spectrum and the associated covariance matrix of two example data sets provided in the directory /Data.
