vaz = 142 (didn't work, try: 142 + 90) (and this didn't seem to change anything – needs more work)
METEK: (from me: manual seems to show +v is perpendicular to N arrow – essentially East)
vaz = 142 + 90 = 232 (seems to be flipped – opposite sign convention? Can we use Gill R2 code?)
I'll try coding all this into cal_files...
