... The idea of an ALFA Virgo Survey is very excited. We should go for full coverage of the Virgo cluster, that is 800 square degrees. ... To interpret and understand the results of such a survey will require a lot of complimentary data. In Milano, we have developed the Galaxy On Line Database Milano Network or GOLDMiNe . ... This site provides on line selection of multiwavelength data for galaxies in both the Virgo cluster and the Coma supercluster. ...

IRAS fluxes at 60 um and 100 um are converted in the so-called far-infrared flux according to the relation: mfir = -2.5 log(2.58 f60 + f100) + 14.75 . where f60 and f100 are IRAS fluxes at 60 m and 100 m expressed in Jansky. ... The term 14.75 comes from the zero-point chosen in RC3 (p.43, Rel. ... The factor 2.58 comes from IRAS Point Source Catalog (1988). ...

... Abstract Compute the geometric state (position and velocity) of a target body relative to an observing body. ... Particulars spkgeo_c computes the geometric state, T(t), of the target body and the geometric state, O(t), of the observing body relative to the first common center of motion. Subtracting O(t) from T(t) gives the geometric state of the target body relative to the observer. ... Index_Entries geometric state of one body relative to another . Link to routine source . ...

... PUL2 catalog contains original absolute proper motions of 59646 stars in 149 fields with galaxies. ... Mean errors of relative proper motions in PUL2 catalog is 5.5 mas/year. ... The external mean error of one relative proper motion of a bright star of PUL2 catalog is 9 mas/year for both of coordinates. ... After issue of UCAC2 catalog, we decided to improve accuracy of proper motions, using Pul-3 coordinates (of 1950s) as the first epoch, and UCAC2 coordinates as the second epoch. ...
