Abstract: In order to address the diversity of millimeter and sub millimeter science that is of interest to astronomers, ALMA has 3 distinct telescope arrays that provide sensitivity to a wide range of angular structures. Separately, one of ALMAs design goals is to be easy to use by astronomers who are not expert at interferometry. As a result the ALMA project presents a very simplified interface to astronomers, which in particular does not make explicit reference to things like array configurations but instead requires astronomers to define a desired resolution, sensitivity, and largest angular scale of interest. Ill discuss some of the subtleties that arise and work the ALMA imaging team is doing to better match ALMA data to scientists desires. One issue which arises which again, is under ALMA project, not PI control is the amount of integration time that will be spent in the various array configurations (12m / 7m / TP). Ill discuss work that has been done to determine appropriate relative integration times and describe the current practices.
Open floor for discussion on other topics as time permits
