Right ascension: 299.4992469952632° Declination: -38.7517655666858° No. sessions: 1488 No. delays: 38163 Defining: Yes RMS(α cos δ) = 2.2418 mas RMS(δ) = 4.3581 mas Cleaned No. sessions: 1269 Cleaned RMS(α cos δ) = 0.2812 mas Cleaned RMS(δ) = 0.3411 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.
