Right ascension: 272.0911911550882° Declination: 45.7057961276139° No. sessions: 272 No. delays: 17949 Defining: No RMS(α cos δ) = 0.2211 mas RMS(δ) = 4.4126 mas Cleaned No. sessions: 206 Cleaned RMS(α cos δ) = 0.1239 mas Cleaned RMS(δ) = 0.1377 mas

Note: Cleaning is a simple outlier elimination algorithm to remove bad sessions. Points whose distance to the mean scaled by the error is larger than 3 are iteratively deleted. The cleaned rms are provided as is and should be taken with some care, especially if the number of sessions is small.
