28 Sep 2006: World Coordinate Systems and FITS Headers. After a mere 20 years the FITS community finally agreed upon a standard way of defining a World Coordinate System (WCS) for telescopes with focal

26 May 2006: The variation measured from faint to bright perturbing star was about 20 counts in the level of the persistent image. ... This indicates that the simple model would only be accurate at the 10-20 counts level.

17 Jan 2006: A reasonable estimate to account for this is that the 2x2 plots need to be adjusted by 20% (ie. ... However, one of the frames exhibited a large magnitude term in y amounting to 0.05 pixel (20 mas) over the observed magnitude range.

26 Jan 2006: The images mimic fuzzy looking galaxies and in this image peak at typically 5-20 counts above sky. ... measured using a conventional method) is therefore also 1.20 (Parseval's Theorem and power spectrum <-- FT --> autocorrelation).

2 Nov 2006: The above plots are all in the WFCAM instrumental system and the 5-sigma limiting magnitudes for stellar objects in this data in this system are approximately Y = 20.9, J = ... 20.6, H = 19.8, K = 19.1 ,all in a Vega system.

27 Jun 2006: The resulting distance moduli are: dmag = [18.2, 20.9, 16.8] In principle, from the CMD matching, you can't really shift the ridgeline by more than 0.05 mag
