  VERITAS observes for ∼750 h and ∼250 h each 
  year during periods of astronomical darkness and par- 
  tial moonlight, respectively. The moonlight observa- 
  tions are almost exclusively used for a blazar discovery 
  program, and a large fraction of the dark time is used 
  for the blazar KSP, which consists of: 
  
  • Four distant (z > 0.3) BL Lac objects recom- 
  
  • A VHE blazar discovery program (∼200 h / yr): 
  Each year ∼10 targets are selected to receive 
  ∼10 h of observations each during astronomi- 
  cal darkness. These data are supplemented by 
  discovery observations during periods of partial 
  moonlight.

  EGRET [12]. 
  
  • A target-of-opportunity (ToO) observation pro- 
  gram (∼50 h / yr): VERITAS blazar obser- 
  vations can be triggered by either a VERI- 
  TAS blazar discovery, a VHE ﬂaring alert (>2 
  Crab) from the blazar monitoring program of 
  the Whipple 10-m telescope or from another 
  VHE instrument, or a lower-energy ﬂaring alert 
  (optical, X-ray or Fermi-LAT). Should the guar- 
  anteed allocation be exhausted, further time can 
  be requested from a pool of director’s discre- 
  tionary time. 
  
  • Multi-wavelength (MWL) 
  
  studies of VHE 
  blazars (∼50 h / yr + ToO): Each year one 
  blazar receives a deep exposure in a pre-planned 
  campaign of extensive, simultaneous MWL (X- 
  ray, optical, radio) measurements. ToO observa- 
  tion proposals for MWL measurements are also 
  submitted to lower-energy observatories (e.g. 
  Swift) and are triggered by a VERITAS discov- 
  ery or ﬂaring alert. 
  
  **5. VERITAS AGN Detections**
  
  VERITAS has detected VHE γ-ray emission from 
  16 AGN (15 blazars), including 8 VHE discoveries. 
  These AGN are shown in Table I, and each has been 
  detected by the Large Area Telescope (LAT) instru- 
  ment aboard the Fermi Gamma-ray Space Telescope. 
  Every blazar discovered by VERITAS was the sub- 
  ject of ToO MWL observations to enable modeling of 
  its simultaneously-measured SED. The known VHE 
  blazars detected by VERITAS were similarly the tar- 
  gets of MWL observations. 
  
  • Distant VHE blazar studies to constrain the ex- 
  tragalactic background light (EBL): Here dis- 
  tant targets are given a higher priority in the 
  blazar discovery program, as well as for the 
  MWL observations of known VHE blazars, par- 
  ticularly those with hard VHE spectra.
