Right ascension: 122.8612804576188° Declination: 1.7811722622567° No. sessions: 518 No. delays: 19236 Defining: Yes RMS(α cos δ) = 0.2874 mas RMS(δ) = 0.2257 mas Cleaned No. sessions: 465 Cleaned RMS(α cos δ) = 0.1679 mas Cleaned RMS(δ) = 0.1842 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.
