Right ascension: 239.8790525639715°
Declination: 3.0800713286808°
No. sessions: 77
No. delays: 1976
Defining: Yes
RMS(α cos δ) = 0.2300 mas
RMS(δ) = 0.2762 mas
Cleaned No. sessions: 76
Cleaned RMS(α cos δ) = 0.2306 mas
Cleaned RMS(δ) = 0.2610 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.
