Mag. is the Integrated Visual Magnitude of the object.
Size is the visual object diameter, in arc minutes.
Area is the visual object area, in square arc minutes.
Const. is the abbreviated name of the constellation where the object is located.

VQ is the Visual Quality, from Meade Instruments:
A - Superb
B - Excellent
C - Very Good
D - Good
E - Fair
F - Poor
G - Very Poor
None - Not yet rated and missing information for computer estimate.
Note: Lowercase letters indicate objects rated only by a computer estimate.
