Version 1.21 - 2012-12-18 (AI)
--------------------------------
- New parameters "withtimerange" and "withpreqgti". With these two parameters 
you can enter a specefic start and stop time through command line (timebegin 
and timeend parameters) or through a FITS file (preqgtifile) to  calculate the attitude.
- Documentation updated.
	
Version 1.20.1 - 2004-03-16 (HB)
--------------------------------
- (config/atthkgen.lyt): old .lyt file used again; "temporary fix" of

closed SPR:
- SSC-SPR-2853: median values calculated incorrectly (as in 1.17.3)

Version 1.18  - 2002-05-23 (MJF)
--------------------------------
- (config/atthkgen.par): updated for `param-2.0'

Version 1.17.2 - 2002-03-10 (MJF)
---------------------------------
 + (odf*/0001_0000000000_SCX00000TCS.FIT): make columns OBTFINE proper "uint16"
   format via TZERO3=32768 and TSCAL3=1 FITS header keywords

Version 1.17.1 - 2002-03-08 (MJF)
---------------------------------
 + (src/atthkgen_mod.f90): added call "OAL_addCommonAttributes()" [SOC-SCR-84]
 + (doc/atthkgen_description.tex): added all OAL calls to section "OAL usage"

Version 1.17 - 2001-12-07 (MJF)
-------------------------------
 + resubmitted 1.16 for start of 5.3 RT

Version 1.16 - 2000-11-28 (AMR)
------------
 + (src/atthkgen_mod.f90) Changed task to calculate instantaneous 
 pointing differences with respect to the median spacecraft pointing 
 (and not to the nominal RA/Dec summary file values) (SSC-SPR-2077).
 + (doc/atthkgen_description.tex) Updated as regards above. 
 
Version 1.15.2 - 2000-11-23 (AMR)
