Summary of the “last-minute” astrometric observing campaign.
| Telescope | Date | CCD | Scale | FoV | Filter | Exp. | N | Seeing | S/N | 1σ (RA) | 1σ (Dec) | Offset (RA) | Offset (Dec) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| OSN 1.5-m | March 2,3,8,10,11, 2019 | 2k × 2k | 0.46″ /pix | 7.5′ × 7.5′ | R-Johnson | 400 s | 109 | 1.6” | 45 | 8 mas | 8 mas | 149 mas | −92 mas |
Notes. Telescope is the telescope used during the observing run. Date refers to the observing dates. CCD is the size of the Andor IKON-L detector. Scale is the binned image scale of the instrument. FoV is the field of view of the instrument. Filter is the filter used. Exp. is the exposure time of the individual images. N is the total number of images. Seeing is the average seeing during the observing runs. S/N is the signal to noise ratio of the object. 1σ (RA) is the average 1σ uncertainty in right ascension (RA) of the astrometry in milliarcseconds (mas). 1σ (Dec) is the average 1σ uncertainty in declination (Dec) of the astrometry in mas. The Offset (RA) and Offset (Dec) are the offsets for right ascension and declination with respect to the JPL#28 orbit expressed in mas.
