Variable stars in original CTI-I survey

This magnitude range corresponds to the saturation limit and the practical faint limit of the original survey (1987-1992). The CTI-I imaged a strip of the sky with a narrow spread of declination over all right ascensions.

The resulting survey area covers a large range of both Galactic latitude and longitude, and includes approximately 50deg^2^. Numerous challenges created by the automated photometry pipeline and associated solutions to these problems implemented during the variable suspect selection process are described. The final list contains 1807 stars.
