Right ascension: 140.2435770345129° Declination: 44.6983291647460° No. sessions: 73 No. delays: 2343 Defining: No RMS(α cos δ) = 0.1307 mas RMS(δ) = 0.2499 mas Cleaned No. sessions: 70 Cleaned RMS(α cos δ) = 0.1234 mas Cleaned RMS(δ) = 0.2459 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.
