Cleaned No. sessions: 20
Cleaned RMS(α cos δ) = 0.5805 mas
Cleaned RMS(δ) = 0.3614 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.
