This package contains tools to read and analyze CCD frames. It has been tested on Python 2.7 and Python 3.4+. Documentation can be found on readthedocs.

Required Python packages are:

• numpy
• scipy
• matplotlib

This installation instructions describe how to create a new virtualenv and install the package into this.

1. Install the following Ubuntu packages:
   • python-numpy
   • python-scipy
   • python-matplotlib
   • ipython
   • python-virtualenv
   • git

2. Prepare install directory:

   We will download and install my Python code into a "special" directory (a virtual environment) in order to not pollute your hard disk.

   1. Create "virtualenv" named ALPS (or any other name and anywhere you like) with:

      virtualenv --system-site-packages --clear ALPS

      and activate it for the current shell session:

      source ALPS/bin/activate

   2. Prepare download directory:

      mkdir ALPS/src

      and go there:

      cd ALPS/src

3. Download and install my packages from GitHub

   1. Download:

      git clone https://github.com/eikevons/alps-ccd.git
      git clone https://github.com/eikevons/plttools.git

   2. Install the packages in the "ALPS" virtualenv (from inside .../ALPS/src/):

      pip install -e alps-ccd
      pip install -e plttools

      Note

      With the -e switch, the packages are installed editable which means that changes to the source code are automatically available in the installed version.

      Alternatively, one can create links to the package directories by hand:

      cd ../lib/python2.7/site-packages
      ln -s ../../../src/alps-ccd/ccd/ .
      ln -s ../../../src/plttools/plttools/ .

4. Test that the install worked.

   1. Start IPython and try to load the modules:

      ipython
      In [1]: import ccd, ccd.io, ccd.analysis, ccd.analysis.hotpixels
      In [2]: import plttools

   2. If you start a new shell, be sure that you activate the virtualenv with source .../ALPS/bin/activate before starting python.
