V       Version Features                           Changes made to Cubism
--------------------------------------------------------------------------------------------
 6.1    Zodiacal spectrum option                     It was noticed that there were lambda
        RA_HMS, DEC_DMS, MJD_OBS added to headers     offsets between SIM I LH input and output
        Orders better spatially-centered              features.  FIX: the sim LH data were the
         according to wavesamp                        problem--DD incorrectly reversed the
        Pointing jitter option (0.4" RMS)             wavelength table for LH.
        Extra noise option to simulate effects
         of flat-fielding
        Sim features better-centered
        Slits are 1 pixel wide
        Data placed from "top" of slit placed at
         the "right" of each order
        Step and Stare ordering updated to 
         reflect what will actually be done

 6.2    Incorporated half-integer pixel steps in     It was noticed that Cubism did not properly
        making Step and Stare maps (LH only).         initiate where to start building the cube;
                                                      the first BCD was displayed in the grid
                                                      middle.  FIX: JD tweaked Cubism...
                                                     HR noticed that the wavelength offsets 
                                                      of v6.1 crept back in.  FIX: DD gave her
                                                      outdated BCDs!
                                                     HR noticed spatial offsets between input
                                                      and output features.  FIX: same as above:
                                                      DD gave her outdated BCDs!
						     HR noticed a few lingering wavelength offsets
						      persist.  Some of the simulated features are
						      reproduced perfectly in wavelength space, 
						      but for some reason the feature at 29.29 um
						      appears in the Cubism-constructed cube 0.06 um
						      short of the expected wavelength.  This trend
						      was verified by moving the feature to other
						      wavelengths; the reconstructed feature still
						      appears 0.06 um short (unlike almost all other
						      features).  FIX: none yet.
