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.
