October 2004: Summary of ASAC response to a charge on large proposals: * The ASAC feels that the best way to handle all large programs (both joint programs and those from a single partner) is to have an international Proposal Review Committee (IPRC) that is empowered to rank and/or choose between large proposals submitted to ALMA in a given semester. * The ASAC feels that scientific duplication in large proposals is to be discouraged. * The ASAC sees no need to invoke a special mechanism for legacy programs at this time with ALMA. * For smaller projects involving collaborators from more than one partner, the ASAC suggests that ALMA adopt a Joint Proposal mechanism similar to the one currently used by the Gemini Observatories. * The ASAC feels that duplicate observations of a given position in the sky should be discouraged unless there are good scientific reasons (variability studies are an obvious exception to this rule). * The ASAC is not concerned about duplication of scientific goals by two or more small programs. October 2005: * The ASAC still believes that a single international Program Review Committee would best serve the ALMA project, minimizing several of the concerns on joint programs and scientific duplication of programs. * The ASAC believes that ALMA will be sufficiently revolutionary that no special provision is required for large or legacy projects. * The ASAC recommends that a small fraction of non-partner applications should be supported, subject to review by the PRC, especially as the ALMA project matures.
