The 2013B call for proposals (http://science.nrao.edu/enews/6.1) details the general capabilities being offered for the Karl G. Jansky Very Large Array (VLA) in the 2013B semester (August 23, 2013 to January 6, 2014) with flexible tuning of sub-band spectral line windows using the 8-bit samplers (enabling up to 2 GHz total bandwidth), use of the 3-bit samplers at higher frequencies in a mode that is suitable for wide-band continuum and extragalactic lines and line searches, use of up to 3 independent sub-arrays and a phased array capability for VLBI.
In addition to the general capabilities, NRAO continues to offer shared risk observing options for those who would like to push the capabilities of the VLA beyond those offered for general use. These are the "Shared Risk Observing" and "Resident Shared Risk Observing" (RSRO) programs. Details of what is being offered for the shared risk programs and what is required to write a proposal for them are available on the web at: https://science.nrao.edu/facilities/vla/proposing/sro2013b.
