All Tables

• Table 1: Observation log with the Asiago and Loiano telescopes.
• Table 2: Observed mean R_C magnitudes and rms deviations for our Loiano and Asiago observations. The last column report the fiducial border line value, discussed in the text, for each source.
• Table 3: Photographic magnitudes. Plates up to 1956 are from the POSS1 survey with 103aE emulsion, later plates are IIIaF from the POSS2 or UK Schmidt surveys.
• Table 4: Photometric, spectral parameters and proper motion significance for the monitored sources.
• Table 5: Summary of variability detection and radio flux densities of the monitored sources. Sources with the flag X were rejected by Londish (2003) because of high proper motion.
• Table A.1: Standard stars used for the magnitude scale definition of each observed field.
