Title:  AGN as Alternate targets

Object: PDS 456, Mk 766, and 3C 445
Exposure:  150 ks, 200 ks, 400 ks
Lead scientist: HLM
[ ] Primary or [X] Backup
Constraints (none/easy/average) NONE
[ ] TOO?

Brief description:

Three AGN would be observed to obtain higher SNR in their existing HETGS =
spectra.  PDS 456 is a bit risky because it was observed once before but =
was faint, so it could be a GO target.  Mk 766 was a GTO target in AO2 =
but only observed for 90 ks and needs much more time.  Similarly, 3C 445 =
had too little signal in the GTO observation of AO13.  There would be no =
constraints on any of these.
