Merge pull request #90 from fact-project/analysis_scripts

Add docstring to theta script

• Add mjd axes

Bug fix for coordinates imports

Fix missing commas

Coordinate Transformations

In fact.coordinates the transformation from camera coordinates in x, y in mm to the Horizontal Coordinate frame is now implemented.

Four utility functions can transform arrays of coordinates from The camera to Horzontal or Equatorial Frame and back

New fact.path

Add new module fact.path
Examples can be found in an ipython notebook

Fixes for io

This release fixes a bug where lists in pd.DataFrame columns got saved as strings in h5py hdf files
and adds the key and columns keyword arguments to read_data, to make it more flexible to use.

Adapt to new naming conventions

We now use the new naming conventions (all keys snake_case, gamma_prediction instead signal_prediction) per default.

v0.10.5

• It's now possible to use to_h5py to add multitple groups to an hdf5 file, default mode is now a instead of w.
  (append instead of overwrite)

• Treat keys like Theta_deg, or Theta_Off_1_deg in split_on_off

Improve split_on_off functions

The results now contain a column to which off region they were selected and off keys are renamed
to their on equivalents.

So for example a result might look like

>>> on, off = split_on_off_source_independet(...)
>>> print(off.head())
off_region Theta 
1               0.2
3               0.5

So first event is from off region 1 and has Theta_Off_1 = 0.2
