Irdap

- Added analysis of master flux frames to enable the user to express the final images in contrast/arcsec^2 or Jansky/arcsec^2
- Restructered code and configuration file to allow for the separate execution of pre-processing, polarimetric differential imaging (previously referred to as post-processing) and angular differential imaging
- Added plot of center coordinates of center frames vs time
- Added possibility to open documentation through terminal command "irdap --website"
- Confirmed that polarimetric data with dithering applied is correctly reduced

Added command-line option to mean-combine final images of different observation blocks

Added the possibility to reduce data taken with the narrowband filters using the existing model of the broadband filters

- Changed the definition of the tuple of the input parameters *annulus_star*, *annulus_background* and *flux_annulus_background*: *width* is replaced by *outer_radius* and the definition of *start_angle* and *end_angle* is now the same as in DS9
- Replaced static flat in Ks by one with P0-90 inserted

First official release of IRDAP + documentation on PyPI and GitHub
