Right ascension: 40.0340602512627°
Declination: -23.1543693818988°
No. sessions: 56
No. delays: 843
Defining: No
RMS(α cos δ) = 1.3729 mas
RMS(δ) = 1.6655 mas
Cleaned No. sessions: 43
Cleaned RMS(α cos δ) = 0.7139 mas
Cleaned RMS(δ) = 0.8450 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.
