Right ascension: 230.4567244757733° Declination: 43.6109077930050° No. sessions: 305 No. delays: 8413 Defining: Yes RMS(α cos δ) = 0.4295 mas RMS(δ) = 0.3934 mas Cleaned No. sessions: 290 Cleaned RMS(α cos δ) = 0.1466 mas Cleaned RMS(δ) = 0.2040 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.
