GSU's PEGA Light Curve Database: 20+ Years Of Blazar And AGN Monitoring

2010 
The long-term broadband variability of AGN has been well known for decades. To investigate this variability further, Georgia State University's Program in Extra-Galactic Astronomy (GSU PEGA) has been amassing optical data on AGN variability for over 20 years. Here, we present details regarding the PEGA database, which contains over 70,000 images for nearly 100 objects. Focusing mainly on blazars, the database contains data on a wide range of timescales, from periodic monitoring to intensive night-long stares. Data reduction and organization are discussed, and light curves for several objects showing significant variability are shown.
