Example light curves for different types of variable sources in the HCV catalog. From left to right and top to bottom, we show the light curves of a classical nova in M87, an AGN in HDF North, a classical Cepheid in M101, SN 2012cg in NGC 4424, an LPV in M31, a RR Lyrae in M31 (phased with P = 0.688 days), two Cepheids in NGC 4424 and NGC 3982 with sparse light curves, and a variable in NGC 4535. Error bars are plotted, although they are sometimes smaller than the symbol size. The variables in the first six panels were observed with the ACS instrument, while the variables in the three lower panels were observed with WFPC2.
