Notes. Gaia DR2 coordinates are for (J2000, epoch 2015.5) and were rounded to 0.000001 degrees, parallaxes and their errors were rounded to 0.01 mas, proper motions and their errors to 0.01 mas yr−1, magnitudes and colours were rounded to 0.001 mag. The initial spectral types with question marks were uncertain because of low S/N or possible problems in the flux calibration of the CAFOS spectra. Further notes on the data:
