Proposal Preparation

Because of peculiarities of the interferometer, proposals must be written with special care. Even at the proposal stage, it is of the utmost importance to provide the following parameters:

• A source list with accurate coordinates.
• A source list with velocities and line width for spectral line observations.
• Observing frequencies.
• Required spatial and spectral resolution, and estimate of required sensitivity.
• For special cases: Required accuracy of the bandpass calibration (e.g., a weak line on a strong continuum, high precision relative astrometry).
• Dates to be avoided during scheduling, because of sun avoidance (a circle of 35 degree radius), phase stability requirements (daytime is often useless in summer), or other reasons (specify).
• Any other stringent constraint (e.g. coordinated observations).

This information is absolutely required to decide about the feasibility of the program, a prerequisite before the program committee can consider the proposal.
