Pip install -r sas_21.0.0_python_packages.txtīefore doing it, please ensure that Python 3.10.6 (or later) is available through the PATH.Īt difference with Perl, for Python it is not necessary to define a SAS_PYTHON environment variable. To perform the installation of all these packages, you can use the following command astroquery>=0.4.3 (v0.4.3 is mandatory !)Īll these packages can be installed by means of pip, the Python package installer, one by one or at once by means of file sas_21.0.0_python_packages.txt, which is included in the SAS 21.0 root installation directory. ![]() Python requirementsīesides Python 3.10.X or later, the following Python packages are required to work with SAS 21.0 The SAS 21.0 initialisation scripts created during the installation take care of the proper initialization of the standard Perl environment variables PERL5LIB and PERLLIB. ![]() Where perl should be the same binary used to work with SAS 21.0. The installation of these modules can be done using the CPAN module included with perl 5.34.1, as follows The following Perl modules are also required: That is accomplished by defining the PERL environment variable to point to such binary, before building or installing Heasoft. Given that Heasoft includes also Perl tasks, please ensure that the installation of this software, either from source code or from pre-built binaries, uses the same Perl 5.30.1 used for SAS 21.0. The SAS installation script configure_install ensures that all SAS 21.0 Perl task's she-bangs use that mechanism to find in PATH, the right Perl binary. Then, before running the SAS 21.0 install.sh script, define the environment variable SAS_PERL to point to the Perl 5.34.1 binary provided by such installation.Īll SAS 21.0 Perl tasks search for the perl binary using /usr/bin/env in the first line of the script ( she-bang). In order to run, they require that a proper Perl be installed in your system and be available through the PATH environment variable.īefore installing SAS 21.0, please install Perl 5.34.1 using the perlbrew tool. Some SAS tasks are Perl scripts, e.g emchain, epchain, omichain, etc. by setting the UB1_PATH environment variable to query the USNO Catalogue. Please do not install WCStools v3.9.5 because its scat tool does not work when going to download data from internet, e.g. The WCSTools web site provides only the source code.Įasy to build from source code. Instructions on how to do it are provided below.īinaries and source code available from Heasoft web site.ĭetails on how to build Heasoft from source code to be compatible with SAS 21.0 can be found below. ![]() On macOS we recommend to install Qt Grace 0.2.6. However, both CentOS and Ubuntu provide binary packages which are easily installed. Installation from source code is difficult. The Grace web site provides only the source code. Please download and isntall the version for X11.
