SAMPLE DATA ENTRY FORM
The sample report form printed on the next page is useful for recording data when using the
differential photometry technique. Basically, this method is to compare the brightness of the
variable star to that of a nearby comparison star, which is known to have no variability. No
attempt is made here to educate the user in all aspects of proper observing procedure and the
associated data reduction. A number of texts about astronomical photometry are available which
describe the proper methodology.
Figure D-1 shows a sample observing report for the night of September 18-19, 2001.
