Right ascension: 23.2740104921182° Declination: -52.0010960550271° No. sessions: 213 No. delays: 3315 Defining: Yes RMS(α cos δ) = 0.5493 mas RMS(δ) = 0.6753 mas Cleaned No. sessions: 176 Cleaned RMS(α cos δ) = 0.3834 mas Cleaned RMS(δ) = 0.4410 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.
