Description
We present a revised and augmented version of the Gonzalez-Perez et al.
[AJ 122 (2001) 2055] catalogue of stars in quasar and blazar fields
calibrated in the Landolt system. Several of the sources in this
catalogue are known TeV emitters and thus of considerable interest for
multifrequency campaigns. A total of 8000 measures in BVRI have been
added, mostly of previously poorly observed fields giving a total of
more than 20,000 measures of stars in 26 fields, in addition to the
22,000 measures of 122 field stars of 13 AGNs in JHK presented in the
published catalogue. The new catalogue flags detected and possible
variables (e.g., Star 8 of 3C66a which appears to be a Mira star of
period 5 years). Deeper exposures have been taken of the fields of the
faint gamma ray blazars PKS0528+13 and PKS1622-29, frequent targets of
multifrequency monitoring campaigns, to improve the quality of their
photometry.
