Examples of TASS Mark IV Data

This page contains miscellaneous examples of image, plots, and numbers derived from the TASS Mark IV cameras. It may change without warning. The best place to find the entire Mark IV dataset is at The Mark IV Database page , maintained by Michael Sallman. You may also find information at the variable star section of the TASS Wiki.

Collected star lists, with good astrometric and fair photometric calibration, taken by Tom Droege in Batavia.

• July, Aug, Sept, Oct, Nov 2002 contain fields between RA = 240 - 270 degrees (July), RA = 270 - 300 degrees (August), RA = 300 - 330 degrees (September). RA = 330 - 360 degrees (October). RA = 0 - 30 degrees (November).
• Data Set 23 contains fields mostly between RA = 90 and 120 degrees, Dec = +7, taken between Dec 3, 2001 and Apr 17, 2002.
