Do you think we are missing an alternative of casacore or a related project?
A suite of C++ libraries for radio astronomy data processing.
Debian / Ubuntu
Casacore is now part of Debian and Ubuntu, use apt to search for the package you need:
$ apt-get update $ apt-get search casacore
Use Homebrew with the
ska-sa tap to install casacore:
$ brew tap ska-sa/tap $ brew install casacore
We now also publish docker images for each github branch on quay.io:
$ docker pull quay.io/casacore/casacore:master
Building from source
Getting the source code
The casacore source code is maintained on github.
You can obtain it using:
$ git clone https://github.com/casacore/casacore
To compile casacore you need to meet the following requirements:
- cfitsio (3.181 or later)
- wcslib (4.20 or later)
- sofa (optional, only for testing casacore measures)
- hdf5 (optional)
- numpy (optional)
- boost-python (optional)
- ncurses (optional)
On Debian / Ubuntu you can install these with:
$ sudo apt-get install build-essential cmake gfortran g++ libncurses5-dev \ libreadline-dev flex bison libblas-dev liblapacke-dev libcfitsio-dev \ wcslib-dev libfftw3-dev
and the optional libraries:
$ sudo apt-get install libhdf5-serial-dev python-numpy \ libboost-python-dev libpython3.4-dev libpython2.7-dev
On CentOS7 you can install these with:
$ sudo yum install cmake cmake-gui gcc-gfortran gcc-c++ flex bison \ blas blas-devel lapack lapack-devel cfitsio cfitsio-devel \ wcslib wcslib-devel ncurses ncurses-devel readline readline-devel\ python-devel boost boost-devel fftw fftw-devel hdf5 hdf5-devel\ numpy boost-python
Obtaining measures data
Various parts of casacore require measures data, which requires regular updating. You can obtain the WSRT measures archive from the ASTRON FTP server:
Extract this somewhere on a permanent location on your filesystem.
In the casacore source folder run:
mkdir build cd build cmake .. make make install
there are various flags available to cmake to enable and disable options:
$ cmake -DDATA_DIR=/usr/share/casacore/data -DUSE_OPENMP=ON \ -DUSE_HDF5=ON -DBUILD_PYTHON=ON -DUSE_THREADS=ON
DATA_DIR should point to the location where you extracted the measures
data. Special variables
%CASAHOME% can be used here, which
can be set at run time through the
You can build python3 support using
-DBUILD_PYTHON3=ON. Note that CMake may
have problems detecting the correct python3 libraries and headers, so probably
you need to set them manually. For
To configure Python2 specific settings use:
PYTHON2_EXECUTABLE PYTHON2_LIBRARY PYTHON2_INCLUDE_DIR
To configure Python3 specific settings use:
PYTHON3_EXECUTABLE PYTHON3_LIBRARY PYTHON3_INCLUDE_DIR
If you run into problems with boost libraries, try setting
-DBoost_NO_BOOST_CMAKE=True. This will be necessary if you have the libraries from NRAO casa in your PATH or LD_LIBRARY_PATH.
