New proper motion determination of Luyten catalogue stars (LTT) with declination between $-5^\circ$ and $-30^\circ$ and right ascension between 0h and 13h 30m

Abstract

Data are given for 353 LTT stars found on 42 areas, covering 25 square degrees each, with declination between 5 and 30 and right ascension between 0h and 13h 30m. Nineteen stars present dierences in proper motion 0 00 10, twenty present dierences in position an- gle 20 and six present those dierences in both values.
