Notes. For each campaign, the receiver and backend are listed, as well as its data span. The data set is characterised by the total observation time Tobs, tot and the centre frequency and bandwidth, f0 and BW of the receiver. We also list the number of frequency channels, Nchn, each observed bandwidth was subdivided into, the mean ToA uncertainty, , and the derived white noise parameters EFAC and EQUAD, that were determined with TEMPONEST. The CPSR-2 recorder independently records two frequency bands (1341 MHz and 1405 MHz) and is thus fit with two sets of EFAC and EQUAD values, one for each band.
