Use VTT for Phase I
People working on their Phase I proposals can use the VTT
for questions such as:
- How many exposures will I need to mosaic my extended target?
- Which of my potential targets "fits best" in the aperture?
- Is there anything interesting I can observe with a coordinated
parallel in another aperture?
- Do any of my potential targets have
n earby bright objects that could spoil the observation?
(There is a "Bright Object" tool within the VTT to help you find
bright objects even if they are not bright on the visual plates.)
- Is there an orientation which would avoid the bright object?
Learning the Unsupported Standalone Version of VTT:
After you have downloaded and installed
the APT, start it up by choosing Programs>APT150>VTT (under
Windows) or type ./VTT at the command line in your home
directory (linux/ unix). A splash screen should appear while the
program loads. Once the program is started you will be presented with
the main VTT screen. Now you can get off to a quick start using the
"Target Tuner Help" in the "Help" menu. In only a few steps you can
have an image loaded and HST apertures overlayed.
