Parallaxes and proper motions. XV

Parallaxes and proper motions are presented for 19 stars in 14 star fields. Five of the stars have no previous parallax determination. Two of these five and three of the remaining stellar systems are wide binaries included in the ADS catalog. Reductions have been made using linear plate constants only, since in earlier parallax solutions it was found that solutions made using this reduction method do not vary significantly from those using the iterative central overlap technique. Results are given to the nearest ten-thousandth of an arcsecond and separately in x and y coordinates along with a combined solution. These practices follow the recommendations and practices of a number of recent investigations.
