Notes. S. D. to JPL denotes (α, δ) standard deviations about the nightly average with respect to the JPL reference ephemeris, after the elimination of outliers. The values in the rms to catalog columns are root mean square residuals from the field stars’ (α, δ) positions with respect to UCAC4. Detailed telescope data for each observatory are given in Table 1.

(a)

Observations at the T100 telescope.

(b)

Observations at the RTT150 telescope.
