CFHTLS Validated Exposures Statistics
|
Last update: Tue Feb 3 11:13:25 HST 2009
Global statistics since the official start (*) of the survey on May 30th 2003 UT (May 29th PM HST, odometer number >= 703900).
The global statistics include the 40 sec. overhead time per exposure following QSO time accounting rules (blue framed table).
* moment when the integration time spent on the CFHTLS started to be accounted for
as the instrumental configuration became stable (improved image quality, guiding, full mosaic)
