Notes.TEMPO2 flags are constructed from these values using the telescope abbreviations, the backend names and the central observing frequency for characterising system noise properties through the ‘group’ flag or the sub-band centre frequencies for determining phase offsets or JUMPS with ‘system’ flags. For example, for a TOA from an observation made at the Nançay Radio Telescope with the NUPPI backend, from the sub-band 1420 MHz when the backend was acquiring its full bandwith around a central frequency of 1854 MHz, the system flag is NRT.NUPPI.1420 and the group flag is NRT.NUPPI.1484. A dash-symbol indicates that no sub-bands were created and the system and group flags are identical. (†)Data from SRT were only included as part of the LEAP mode of observations for this data release.
