Psrsalsa

PSRSALSA - A Suite of ALgorithms for Statistical Analysis of pulsar data

See http://www.jb.man.ac.uk/research/pulsar/Resources/psrsalsa.html for some instructions and a tutorial.

DOWNLOAD/UPDATE

Download the latest version from https://github.com/weltevrede/psrsalsa/ which can be done on the command line with: git clone https://github.com/weltevrede/psrsalsa.git This will make a directory psrsalsa/

To update existing code you can run: git pull

When the code is updated, do a "make clean" and run "make" to compile the code again.

INSTALLATION

In principle running "make" in the directory where this README.txt file lives should be enough. However, since PSRSALSA depends on other libraries, the Makefile might require editing. These dependencies include:

• cpgplot
• cfitsio
• fftw3
• gsl See below for a description of those dependencies.

The entries in the Makefile that might need editing are:

• The LIBS variable.

  The following libraries are directly used by the code: libcfitsio, libcpgplot, libgsl and libfftw3f.

  However, they might depend on other libraries themselves and which ones is system dependent.

• The LIBDIRS variable.

  If libraries are located in a place the compiler does not look by default, they can be defined with this variable. By default, it is adding the location which is set by the PGPLOT_DIR environment variable.

• The INCDIRS variable.

  If header files are located in a place the compiler does not look by default. Again, by default it is adding the location which is set by the PGPLOT_DIR environment variable.

• GSLFLAGS variable

  The library version of the GSL library you use can be specified with the -DGSL_VERSION_NUMBER=XXX. Changing this number enables/disables different pieces of the code, such that the code is compilable agains a range of versions. The functionality of the code might be restricted depending on the version of GSL you're compiling the code against.

DEPENDENCIES

• cfitsio:

Website = http://heasarc.gsfc.nasa.gov/fitsio/fitsio.html

Probably your linux distribution allows you to download this package.

Version 3.21 is known to work.

• fftw3:

Website = http://www.fftw.org/

Probably your linux distribution allows you to download this package. Make sure to compile/obtain the float version of the library as well: libfftw3f.

Version 3.2.1 is known to work.

• gsl:

Website = http://www.gnu.org/software/gsl/

Probably your linux distribution allows you to download this package. You need libgsl and libgslcblas.

Version 1.15 is known to work

• pgplot:

Website = http://www.astro.caltech.edu/~tjp/pgplot/

Probably your linux distribution allows you to download this package. This library probably depend on other libraries, such as libgfortran, libX11 and libpng.
