VizieR Online Data Catalog: Faraday rotation of Northern hemisphere pulsars (Ng+, 2020)

CHIME is a radio telescope hosted by the Dominion Radio Astrophysical Observatory (DRAO) in British Columbia, Canada. CHIME operates across a wide bandwidth of 400-800MHz and has a collecting area (~80x100m²) and point-source sensitivity comparable to that of other 100-m class radio telescopes. The reflecting surface of CHIME consists of four parabolic cylinders. It is a transit telescope with no moving parts. For the CHIME/Pulsar project, we combine the signals from the 1024 dual polarization feeds and form 10 tied-array beams that are available as raw voltages (Ng 2018IAUS..337..179N). This means that we can track 10 different pulsars at any given time as they transit through CHIME's field of view, along the meridian. This provides very high-cadence scheduling: while many of the Northern hemisphere pulsars are being monitored daily, the longest cadence to cycle through all sources in the northern sky is only ~10d. This is reflected in the long co-added integration length of our data (Total_fold) and the high signal to noise (S/N) achieved as listed in Table A1. The transit time of each source is a function of the declination; transit times can range from tens of minutes to hours for circumpolar sources. CHIME can in principle observe down to a declination of -20°.
