Beginning of ReadMe : I/110 Occultation Double-Star Observations (Evans 1983) ================================================================================ Catalogue of Occultation Double-Star Observations Evans D.S. <IAU Colloquium No. 62, Current Techniques in Double and Multiple Star Research, Lowell Obs. Bull. 167, p. 73 (1983)> =1983LowOB...9...73E (Bull. 167, Volume 9) ================================================================================ ADC_Keywords: Stars, double and multiple ; Occultations Description: This catalog contains data on 224 double stars observed photoelectrically during lunar occultations. The author cites the advantages of this method of double star detection as increased resolution, accuracy of the vector separations of roughly one-half arcsecond or better, and the opportunity to make photometric determinations of the magnitude differences between components. The vector separation is the true separation projected along a line perpendicular to the actual lunar limb. The catalog is a compilation of twelve years of observations from the literature (through roughly 1980). It is divided into three files. The first file, data1.dat, contains information on stars brighter than visual magnitude 6.7. The second, data2.dat, lists SAO catalog stars fainter than magnitude 6.7. The third file, data3.dat, contains data on faint stars with no SAO number. For these stars, data on their magnitudes or spectral types may be absent. In many cases there are multiple records per star, reflecting separate observations. The records are arranged by SAO number or other identifier, and contain visual magnitudes, spectral type, observing run number, a subjective grade of the probability of being double, the vector separation with computed error, position angle, and the lunar limb slope and its error. It also includes the magnitude difference between the components in (somewhat arbitrarily assigned) blue and red band passes. In the case of a triple star, the run number is repeated and the data for the triple given with magnitude differences from the brightest star.
