--------------------------------------
Main changes from AIRY 5.0 to AIRY 5.1
--------------------------------------

-----------------
PART A - Modules:
-----------------
CBD:
  - The output's order has been exchanged: (WAS) top=PSF, bottom=OBJ, 
    (NOW IS) top=OBJ, bottom=PSF, as it is in the whole Soft.Pack.AIRY.
    Please note that this will cause compatibility problems with already existent
    projects. You must re-edit your projects and switch the two outputs.
   
OBJ:
  - New sub-GUIs for Planetary Nebula, SNR, Spiral galaxy, YSO, 
    and user-defined objects. 
  - Bug fixed in parameter restoring procedure (esp. Planetary nebula and SNR).
  - small changes in the text of the GUI.
  
PEX: 
  - small changes in the text of the GUI.
  - file "find_dim.pro" has been deleted [not really used].
  - files "circular_mask.pro", "psf_extrapolation.pro", "append.pro",
    "remove.pro", and "circle.pro" have been renamed by adding the prefix
    'pex_' to each filename. Apt changes to the functions/procedures.

RFT:
  - file "rft_time_gui.pro" and folder "rft_gui_lib" removed [unused and no 
    more necessary]
    
-------------------------------    
PART B - Known-Issues Resolved:
-------------------------------
1- Problems may occur depending on the browser/OS combination when the html help
is called from the modules GUI. Hence we recommend those combinations:
   - Windows+Internet Explorer,
   - Mac-OSX+Safari,
   - Linux+Firefox Mozilla. 
(Resolved by using the "online_help" procedure instead of the old way of calling 
the AIRY_HELP)

2- In OBJ module, the "Object total magnitude" field within the sub-GUIs "YSOs"
and "Spiral galaxy" remains to the original value although it has been changed
and the whole set of parameters was saved before. 
This is just a display problem, since the change of this value is effectively 
taken into account (as it can be seen from the IDL/CAOS prompt line).
