Observed in only 3 session(s)

Right ascension: 254.8506226643370° Declination: 26.4935952781582° No. sessions: 3 No. delays: 205 Defining: No RMS(α cos δ) = 0.0297 mas RMS(δ) = 0.1073 mas Cleaned No. sessions: 3 Cleaned RMS(α cos δ) = 0.0297 mas Cleaned RMS(δ) = 0.1073 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.
