| The Multifrequency Snapshot Sky Survey (MSSS) is the first major observing program to be carried out with LOFAR during its ongoing commissioning phase. The primary goal of MSSS is to produce an accurate and detailed low frequency sky model, which will be used as the basis of calibrating images produced in the future by LOFAR. Along the way, the process of making MSSS possible is an efficient way of shaking down telescope operations! Having gotten this far is the result of the efforts of a large number of people working on LOFAR at all levels.
The image shows the current state of the MSSS observing program (as of the middle of November 2011). So far, nearly 10% of the nominal LBA survey area has been observed. Tests of the processing pipeline are underway using these data sets, and the pipeline itself is under active development.
To keep up with the progress of MSSS observing, you can check at this page, which features a regularly updated version of the map shown above. More information about MSSS itself is available here on the main ASTRON website.
Stay tuned for more updates as the survey progresses!
