Observed in only 4 session(s)

Right ascension: 189.3134948017673° Declination: -50.7731039157814° No. sessions: 4 No. delays: 13 Defining: No RMS(α cos δ) = 15.5727 mas RMS(δ) = 2.4451 mas Cleaned No. sessions: 4 Cleaned RMS(α cos δ) = 15.5727 mas Cleaned RMS(δ) = 2.4451 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.
