Description:
   We report CCD measurements of 33 visual double stars observed at the 1-meter
   coude reflector of the Observatorio de Llano del Hato located at Merida,
   Venezuela. We also present an algorithm to determine the stars' centroids
   for superimposed images as well as a brief comparison of accuracies attained
   by the algorithm and the program CENTER of the IRAF package.
