5005A V/5A Colours, Luminosities, and Motions Nearer K-M Giants O J Eggen Royal Obs. Bull. No. 125 ??? ??? 1966 1966QB4.G85n125.... Colors Space velocities Stars, giant Stars, late-type The data compilation Colours, Luminosities and Motions of the Nearer Giants of Types of K and M (Eggen 1966) contains all stars in the Yale Catalogue of Bright Stars (Hoffleit 1964) that have visual magnitudes brighter than 5.5 and that have been observed to have B-V redder than +0.8 mag, with the exception of a few K-type dwarfs. In addition to mostly K- and M-type giants, a few subgiants and supergiants are included. The data result from some 1600 photoelectric observations of 600 stars with the 50.8-cm reflector of the Hale Observatories. Approximately one-third of the stars had been observed at the Cape Observatory (Cousins and Stoy 1963). Although spectral types are given in the published catalog, they were taken from a variety of sources, are very inhomogeneous, and are not included in this catalog.

HR HR number from the Yale Catalogue of Bright Stars (Hoffleit 1964). --- HR2 A slash (/) and additional digit if a second HR star is included in the measurements. --- flag1 An asterisk (*) is present if there are remarks in the published catalog. --- GCRV GCRV number in the General Catalogue of Stellar Radial Velocities (Wilson 1953). --- GCRV2 A slash and additional digit if a GCRV star is included in the value given --- V Photoelectric V(E) magnitude. The precision varies within the data field. mag flag2 A "v" if the magnitude is variable; a colon (:) for uncertainty. If the magnitude given is considered to be a maximum, a code M is given in byte 46. --- B-V B-V color. The precision varies. mag flag3 uncertainty flag: colon (:) for uncertainty, "V" for variable. --- U-B U-B color. The precision varies. mag flag4 U-B flag (see byte 32). A question mark (?) is present if the value is surrounded by parentheses in the published table. --- ObsNum Number of observations, n, for UBV data. --- UBVcode Code for UBV measurements Code for UBV measurements C observed at the Cape Observatory (Cousins and Stoy 1963) H observed with the 100" telescope (no number of observations given) M variable magnitude reported is considered to be a maximum value for the variable star --- M(V) Absolute visual magnitude, M(V), taken from various sources, as indicated by the codes in bytes 53-54. Precision varies. mag flag5 Flag for M(V) Flag for M(V): : M(V) uncertain ? M(V) very uncertain No source is given for very uncertain values, nor for many of the other values quoted (53-54 blank). --- Source Source of M(V) Source of M(V), as denoted by the following codes: Cp available photometry of common proper-motion companion used to obtain distance moduli and luminosities H luminosity derived from probable membership in the Hyades group Tr not defined in source reference W Calibration of M(V) (W) used to derive M(V) (see page E152 of source reference) * values obtained by Gyldenkerne (1964) from photoelectrically determined luminosity parameters The source is not defined in the absence of a code. --- u- Sign of U component --- u U component of the space velocity relative to Sun. km/s u_u Colon if U uncertain. --- v- Sign of V component --- v V component of the space velocity km/s u_v Colon (:) if V uncertain. --- w- Sign of W component --- w W component of the space velocity km/s u_w Colon (:) if W uncertain. --- C.-H. Joseph Lyu Hughes STX/NASA 1995Aug16 UNKNOWN UNKNOWN The original ADC documentation by Warren, Jr. (1986) was used to generate this ReadMe file. The data compilation Colours, Luminosities and Motions of the Nearer Giants of Types K and M was received on magnetic tape from the Centre de Donnees Astronomique, Strasbourg (CDS) on 9 July 1980. Text records at the beginning of the original file indicated that the data were punched in 1972 November at the Kanazawa Institute of Technology. The following modifications were made to the data file to standardize the format, to make the data easier to machine process (e.g., to separate character and numerical data fields) and to effect closer agreement between the published table and the machine format. 1. A catalog number "5005A74" assigned by the CDS was removed from the beginning of each record. Thirty-two text records containing a column (not byte) description and possible format for reading the data were removed entirely from the file, since their presence would have made the file more complicated to machine process and not sortable. 2. The remarks flag (byte 7) was moved from byte 5 so that it always occurs in the same position. This was previously not the case because of the data in bytes 5-6. 3. Decimal points were added to all V(E), B-V, U-B and M(V) data, the variability indicator "V" for V(E) was changed to lowercase "v", and plus signs were added to all positive values of B-V, U-B, M(V), U, V, and W. 4. The code "C" for number of observations was moved from byte 45 to byte 46 (to remove it from the numerical field) and the codes "H" and "M" for 100" and "max." occurring in the published table, were added. 5. The question mark for M(V) was moved from one of the sources bytes (53) to byte 52 to isolate it from the sources codes. The M(V) source codes CP and TR were changed to Cp and Tr, respectively, to agree with the published table. 6. The last five stars (HR 9066-9089) were missing from the file -- these were added. A few errors were found in the data during the course of this work and have been corrected, but the machine version has not been proofread. Therefore, if unusual values are found in the machine version, they should be checked against the published table before any interpretation is made. -------------------------------------------------------------------------------- V_5A.xml
