... Number2
The red CLASS/red CLIC is a "radio Julian date" (or "Jansky Julian date"), which starts as $-2^{15}$ on the date of the first radio observation by Karl Jansky. It is thus the Modified Julian date minus 60549. That choice was made to maximize the time interval over which radio astronomical data could be usefully stored in an integer*2, back when 2 bytes of header space per spectrum were a significant consideration. This date has little meaning outside the rather sparse community of souls gathered around the red CLASS and red CLIC programs, however...

... antennas7
If there were no pointing errors, a single-dish of the same size as the interferometer antennas would be strictly sufficient.

this is probably too much, and would most likely lead to instability in the model fitting !..

The combination is only optimal if the spectral index has no spatial variations. A better handling of spatially variable spectral index is under study.

ultimately, a similar DD, SS, DS and SD pseudo-Stokes polarization set may be added for circular polarization. D is the first letter for Dexter, the Latin name for Right, while S is the first letter of Senester, the Latin name for Left.
