Abstract

The Expanded Very Large Array (EVLA) project is the next generation instrument for high resolution long-millimeter to short-meter wavelength radio astronomy. It is currently in early science operations, with full science operations to commence in January 2013. The EVLA construction project provided new software for all aspects of operation of the telescope, including both that required for controlling and monitoring the instrument and that involved with the scientific workflow. As the telescope transitions into full operations we are also developing the software and operations policies that allow us to manage the large amounts of data collected by the instrument (up to terabytes for a single observation; petabytes per year for all observations). We present an overview of our data management software and policies for the EVLA, as well as some early experience we have gained with the storage and distribution of data, post-processing, automatic processing, and centralized reprocessing of data, and storage of derived products back into our science archive.
