TL;DR
This paper presents multi-band photometric light curves of two BL Lac objects, PKS 0537-441 and PKS 2155-304, observed over two years, providing valuable data for understanding their variability.
Contribution
It provides the first comprehensive multi-band optical and near-infrared light curves for these objects over a two-year period.
Findings
Detected variability in both objects across all bands
Identified correlated flux changes between optical and near-infrared
Provided data for future variability and emission mechanism studies
Abstract
We report the 2006-2008 light curves obtained with the REM telescope in VRIJHK bands for the two BL Lac objects PKS 0537-441 and PKS 2155-304
