Simple Mapping Project

A project to produce radio brightness maps of the sky over head using the DSES upper dish has been underway since early 2006. Measurements are being taken at the neutral hydrogen frequency HI (21 cm or 1420 MHz) and the map is being built up by doing 24-hour meridianal drift scans at 1 degree increments of declination each day. Details of the project plan and a sample of the preliminary results are shown below.
