Right ascension: 287.7902204408015° Declination: -20.1153080669836° No. sessions: 1201 No. delays: 21833 Defining: Yes RMS(α cos δ) = 1.2497 mas RMS(δ) = 4.8204 mas Cleaned No. sessions: 1096 Cleaned RMS(α cos δ) = 0.2694 mas Cleaned RMS(δ) = 0.5461 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.
