Faint UBVRI CCD sequences for wide-field surveys - II. UBVR sequences at delta =-30 degrees

We present results from a continuing campaign to secure deep multi-colour C CD sequences for photometric calibration in UK Schmidt fields with galactic latitudes \b\ > 50 degrees, In this paper we present UBVR photometry in 12 fields and BR photometry in a further 14 fields observed within UK Schmidt survey fields centred at delta = -30 degrees, Photometric errors are at th e 0.05 level at 20.2, 21, 20.5 and 20 mag for UBVR sequences respectively. Our observations were carried out with the 0.9-m telescope at the Cerro-Tol olo Inter-American Observatory. These data are not intended for use as high ly accurate individual photometric standards, but rather for use as sequenc es, using a large number of stars to calibrate wide-area data such as photo graphic plates, The data are available electronically at http:// icstar5.ph .ic.ac.uk/similar to sfroom/phot/photem.html.
