Observed in only 2 session(s)

Right ascension: 254.9374885437160° Declination: 2.2186232210921° No. sessions: 2 No. delays: 125 Defining: No RMS(α cos δ) = 0.0345 mas RMS(δ) = 0.0219 mas Cleaned No. sessions: 2 Cleaned RMS(α cos δ) = 0.0345 mas Cleaned RMS(δ) = 0.0219 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.
