Observed in only 2 session(s)

Right ascension: 250.5220454967781° Declination: -20.1235692588269° No. sessions: 2 No. delays: 134 Defining: No RMS(α cos δ) = 0.0273 mas RMS(δ) = 0.0605 mas Cleaned No. sessions: 2 Cleaned RMS(α cos δ) = 0.0273 mas Cleaned RMS(δ) = 0.0605 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.
