Observing Log ============= This file describes the images that make up the raw and reduced datasets from the KPNO 2.1-m telescope acquired on UT 2-9 July 2005. The instrument was SQIID. J, H, and K band images were obtained simultaneously for each frame number. Two targets were observed: the comet Tempel 1, and the Persson et al. (1998) [PERSSONETAL1998] standard star field S791-C (RA = 13h17m29.6s, Dec = -05d32m37s). Resulting photometric data were published by Knight et al. in Icarus in 2007 [KNIGHTETAL2007]. UT July 2, 2005 =============== Night 1 of 8. Partly cloudy. Total images: 24 (12 comet frames and 12 sky frames). No standard stars were taken due to clouds. Frames Object Exp.
