Right ascension: 255.2214752546870° Declination: -26.1810348995835° No. sessions: 534 No. delays: 14980 Defining: Yes RMS(α cos δ) = 0.3607 mas RMS(δ) = 0.4343 mas Cleaned No. sessions: 497 Cleaned RMS(α cos δ) = 0.2649 mas Cleaned RMS(δ) = 0.2303 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.
