Photoelectric B and V sequences to 21st magnitude in 17 medium- and high-galactic-latitude regions

Deep photoelectric sequences have been obtained to the 21st B and V magnitudes in 17 regions at galactic latitudes ranging from -45 deg to +86 86 deg. The observations were carried out using the prime-focus of the Canada-France-Hawaii telescope at Kitt Peak. The plates are used to study the large scale distribution of quasars; the redshifts and clustering properties of faint galaxies; and the characteristics of faint stars in the Galaxy. Finding charts and tables listing the B and V magnitudes of the objects (typically 30-40 per field) are given. The precisions of the observations are discussed. It is expected that the accuracies of the calibrating sequences are of the order of 0.05 mag. 9 references
