Abstract

 

Twelve Stars in VSF 193 in Sagittarius were studied. These objects were all long period variables which have previously been studied, but which for various reasons needed revising or updating.

 

Nine of the variables have two or more published periods. By analysis of all previously published available data, combined with estimates from our own plate collection, I have been able to update these nine stars. In most cases I have been able to make a definite choice between the alternate periods and to improve upon the one chosen.
