The Hamburg Quasar Monitoring program (HQM) at Calar Alto. II. Lightcurves of weakly variable objects

SCHRAMM K.-J., BORGEEST U., KUEHL D., VON LINDE J. and LINNERT M.D.

Abstract (from CDS):

HQM is an optical broad-band photometric monitoring program carried out since Sept. 1988. We use a CCD camera equipped to the MPIA 1.2 m telescope. Fully automatic photometric reduction relative to stars in the frames is done within a few minutes after each exposure, thus interesting brightness changes can be followed in detail. The typical photometric error is 1-2% for a 17.5 mag quasar. We here present lightcurves already evaluated but not shown in Paper I. We also discuss existing literature data.
