Time system is year, number of month and date with decimals in U.T.
Observations are Pogson step estimates. Magnitudes are derived from
these estimates by using the sequence below. CL = class: estimated
accuracy of observation; 1 = good, 2 = fair, 3 = poor. Instrument
(type, aperture in mm and magnification): C = catadioptric telescope
(SCT), L = refractor, B= binoculars.
Identifications and visual magnitudes of comparison stars are from
BAA.VSS.
