Right ascension: 140.6934094162968° Declination: -39.9930745350822° No. sessions: 727 No. delays: 8866 Defining: Yes RMS(α cos δ) = 0.6220 mas RMS(δ) = 1.0817 mas Cleaned No. sessions: 633 Cleaned RMS(α cos δ) = 0.4277 mas Cleaned RMS(δ) = 0.8076 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.
