Observations and Observing

Last updated 2645 days ago by Russ Taylor Comments (2)

To cover the entire sky visible from Arecibo will require 12 GALFACTS runs, consisting of 8 main regions north and south of the Zenith and four smaller regions at the Zenith. Each run occupies slightly more than 6 hours of right ascension (including a small amount of overlap). The areas of each of the eight main regions superposed on the Bonn 1420 MHz continuum survey is shown in the figure below. Click on the image for a higher resolution view. GALFACTS observing have been completed for all main runs (N1, N2, N3, N4, S1, S2, S3 and S4), and four zenith strips (Z1, Z2, Z3,  Z4) as of 26 November 2013.
