Applying for Time

The TTF can be used on the Anglo-Australian Telescope (AAT) (at Siding Spring Observatory) and William Herschel Telescope (WHT) (at La Palma).

Astronomers interested in using the instrument might also like to check out the proposal guidelines for Anglo-Australian Telescope observing proposals. Application deadlines for the Australian Time Assignment Committee occur in April and October each year. More information about the application procedure can be found from the AAO Web page on this subject.

There is a web-based Signal-to-Noise performance calculator for TTF. Parameters for an observing run can be input to obtain exposure time and signal-to-noise ratio estimates.

There are also signal-to-noise calculations showing the sensitivity of TTF when used with both the MITLL and Tektronix CCDs. Calculations have been made for a number of different CCD operating temperatures.

It would really help if, in your proposal, you make absolutely clear whether it is point sources or diffuse emission that most interests you. There are ways to optimize the actual observing strategy for either angle. If you want both sorts of emission, what spatial or kinematic resolution are you after, what photometric accuracy,  etc.
