Seeing Statistics

The robotic differential image motion monitor (RoboDimm) is now operating since more than a year. Its calibration has been verified during long parallel measurements with the former DIMM, which in turn has been calibrated during a campaign with the generalised seeing monitor (GSM, Aziz Ziad from the Université de Nice).

For the period January 2005 till October 2011 the median seeing has been determined to be 0.80 arcsec. The statistics results from 522373 data points.

Former Periods:
April 2001 till December 2002
April 2001 till December 2003
April 2001 till May 2004
June 2001 till Sept 2005
