Notes. nsc is the number of self-calibration iterations adopted. Those with a final iteration of amplitude self-calibration are denoted with the ‘a’ suffix. θmaj, θmin, and BPA give the major and minor full-width-half-maxima (FWHM) of the synthesized beams. θreq is the requested beam size, and gives the ratio of the synthesized to the requested beam area; larger numbers imply poorer resolution. σMAD and σreq are the measured and requested RMS sensitivity, respectively, and σMAD/σreq is the excess noise in the image over that requested. σMAD is measured on the cleanest images. DRpre and DRpost are the dynamic range, Speak/σMAD, for the pre- and post-self-calibration data; DRpost/DRpre gives the improvement factor.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
