Radio Astronomy, Arecibo, and using ALFA and L-band Wide for ALFALFA

Introduction

The A2010 observers' page at Arecibo An introduction to CIMA for ALFALFA ALFALFA introduction to the Arecibo telescope The Arecibo L-band Feed Array ALFA A bit about angular resolution, diffraction limit, etc. The ALFALFA centroiding accuracy Rotating ALFA for ALFALFA The ALFALFA observing mode The ALFALFA two pass strategy The complications of precession

The ALFA drift scans for the ALFALFA survey were completed on October 26, 2012, after 6.5 years, 4,741.5 hours and 808 observing runs. You can read about the final observing run on the ALFALFA blog. Starting in 2012, we began a coordinated campaign of followup targeted observations using the L-band wide receiver.
