Abstract:
   Presents the data part of work concerning the age, metallicity, and 
   distance of three globular clusters, which are believed to belong to the 
   disk system of galactic globular clusters, NGC 6496, NGC 6624, and NGC 6637
   (M69). Information is given on: the observations, the reduction, the 
   photometric calibration. A new photoelectric sequence around NGC 6496 is 
   presented as well. The present data are compared with previous work. 
   Finding charts as well as recipes for cross identification are given. Lists
   containing the brighter stars in the cluster regions are added.
