Notes. All filter values, CWL and FWHM, are in nanometers. Columns are, respectively: source identification, date of observation in calendar format for year-month-day, date of observation in Modified Julian Date (MJD) format, central wavelength (CWL) of the filter used, full-width at half-maximum (FWHM) of the filter used, exposure time in seconds, approximate target azimuth (degrees), approximate target zenith distance (degrees), standard deviation in right ascension and declination in milliarcseconds of the differences between the observed and catalogue positions for the UCAC2 stars, number of reference stars, and number of observations. Transmission data concerning the ESO broad band red filter (#844) used in this work can be found at http://www.eso.org/sci/facilities/lasilla/instruments/wfi/inst/filters/. Transmission data concerning the SOI red filter (R Bessel) used in this work can be found at http://www.soartelescope.org/observing/soi-filters. Azimuth convention: North is zero, East is  + 90°. Source 0138−097 was observed in two different dates and all concerned CCD frames were treated together for astrometry.
