... 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. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
