VizieR Online Data Catalog: Multi-epoch VLBA imaging of 20 Tev blazars (Piner+, 2018)
Abstract
The bulk of the observations come from the Very Long Baseline Array (VLBA) experiments S6117 and S7017 during the years 2013 to 2015. These two experiments together observed each of the 20 sources from Table 2 at four epochs separated by about 6 months, for a total of 80 images. These observations were made at an observing frequency of 8.4GHz (4cm). We also obtained images at 15.3GHz during experiment S7017 of the two sources 0033+595 and 0647+251.
In order to extend the measured time baseline for some sources, we also included some earlier images from 2009 and 2010 recorded during experiments BE055 and BE057 and originally published by Piner & Edwards (2013EPJWC..6104021P). Altogether, these observations yield a final data set consisting of 88 images of 20 sources obtained over the years 2009-2015 and totaling approximately 200hr of integration time on the VLBA.
