Right ascension: 115.5114539762028° Declination: 49.0043358109738° No. sessions: 139 No. delays: 7393 Defining: Yes RMS(α cos δ) = 0.1910 mas RMS(δ) = 0.1609 mas Cleaned No. sessions: 132 Cleaned RMS(α cos δ) = 0.1287 mas Cleaned RMS(δ) = 0.1602 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.
