summarize_tracklet

ssapy.correlate_tracks.summarize_tracklet(arc)[source][source]

Compute mean ra/dec, uncertainty in mean, proper motion, uncertainty for a short arc.

Parameters:

arc (the short arc of detections) –

Returns:

[(ra, dec), (dra, ddec), (pmra, pmdec), (dpmra, dpmdec)]
ra, dec (the mean position in right ascension and declination)
dra, ddec (the uncertainty in the mean RA and declination)
pmra, pmdec (the proper motion in right ascension and declination)
dpmra, dpmdec (the uncertainty in the proper motion in RA and declination)
