The 10-cm Sleuth telescope (Palomar Observatory, California) and the 10-cm Planet Search Survey Telescope (PSST; Lowell Observatory, Arizona).
The PSST detector is a thinned, back-illuminated 2048x2048 Loral CCD with 15-micron pixels (Dunham et al. 2004). The Sleuth detector is a Marconi 2048x2048 13.5-micron-pixel back-illuminated CCD camera.
The two telescopes monitored a 5.7° x 5.7° field of view centered on the star 16 Lyr (19h 01m 26.3713s +46d 56m 05.325s).
Sleuth utilitizes an SDSS r filter, whereas PSST uses a Johnson R filter. The integration times for our exposures were 90s.
Standard IRAF tasks or customized IDL routines were used to calibrate the images from the two telescopes. Differential image analysis was applied to each of the separate photometric data sets using a pipeline based in part on Alard (2000). The two data sets were then combined by matching the stars in each field of view. Transit detection was performed using the box-fitting transit search algorithm of Kovacs et al. (2002).
The data parameters fall into the following approximate ranges:
|RA (2000)||18 43 1.8||19 19 30.8|
|Dec (2000)||+43 54 23.0||+50 00 00.0|
|HJD of the
|Total number of stars||-||25947|
|Number of epochs||-||~15000|
