MRAO 6C Survey Zone II
Abstract
This project contains 20 512 x 512 images giving coverage of the zone specified (see Figs. 3, 5, and 10 of the reference). The images are grouped into sets of four, designated A, B, C, and D, about each of five map centres: 0940 41, 1120 41, 1300 41, 1440 41, and 1620 41. For each map centre, images A, B, C, and D are on a common grid with A (top left), B (top right), C (bottom right), and D (bottom left). Their mutual overlap can be inferred from the (u,v) range specified in the FITS headers [(u,v) being an internal (x,y) grid-aligned coordinate system for that map center]. Users should avoid the outer 50-pixel border of each image, as this is subject to edge effects.
