BBarolo 1.6

Major changes:

• New task SMOOTHSPEC to perform spectral smoothing of a datacube with a filtering window. The new task incorporates the old HANNING task, which is now deprecated.

• Added basic utilities to perform operations on FITS file, including "modhead", "remhead", "listhead", "fitscopy" and "fitsarith". These functions will be handy to make a datacube compatible with BBarolo. Typing "BBarolo --fitsutils" from the command line gives information on these new utilities. See also documentation for v1.6.

• Added support for long options from the command line. New options are also available, including "-d taskname", "--list", "--cline". Typing "BBarolo -h" from the command line gives information on the new options.

• 3DFIT task: New reverse-cumulative fitting algorithm for highly-inclined galaxies (inc>75 deg). Can be enabled with REVERSE=true. This algorithm is experimental and sometimes it fails....use it wisely!

• 3DFIT task: for the second stage fitting, it is now possible to regularize the various parameters with different functions. Type of regularization can be chosen with the new REGTYPE parameter, which substitutes the old POLYN parameter. POLYN is for now preserved for backward compatibility.

• New parameters NORMALCUBE, DELTAVROT, MINVDISP, BADOUT for 3DFIT task (see 3DFIT documentation).

• New algorithms for fully automated execution.

• GALMOD task: the flux of the model is now consistent with the input surface-density profile for HI emission in Jy/beam.

• The source finder now can produce sub-cubes and sub-maps of each detection (CUBELETS parameter) and plots of each detected sources.

• Improved output plots, including new colormaps and new plots for SPACEPAR task. Fixed a problem with axis ticks in matplotlib 3+

• pyBBarolo: added SpectralSmooth() class and new BBaroloWrapper() class for general execution of BBarolo.

• Bug fixing: the usual bazillion bugs have been fixed thanks to the users who report them! Thank you!
