Observed in only 4 session(s)

Right ascension: 251.0671682261930° Declination: -77.2635591171946° No. sessions: 4 No. delays: 19 Defining: No RMS(α cos δ) = 1.1947 mas RMS(δ) = 0.5111 mas Cleaned No. sessions: 4 Cleaned RMS(α cos δ) = 1.1947 mas Cleaned RMS(δ) = 0.5111 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.
