Inner 3..'42".5  [[symbol - star symbol]] North of [[symbol - comet symbol]]
Outer 3..36.0 
By the second Set
Inner 2..42.9 [[symbol - star symbol]] North of [[symbol - comet symbol]]
Outer 2..38.1

By first Set 2^[[m]]..40^[[s]].45 [[symbol - comet symbol]] East of [[symbol - star symbol]]
By second Set 2..40.90

These are not corrected for Refraction 
dec = 0".8 = d[[sigma]]
