Parkes observations for project P885 semester 2019OCTS_10

Brief description

We propose to observe the magnetars 1E 1547.0-5408 and PSR J1622-4950
approximately weekly, to track their rotation, flux density, and
polarisation, as we have been doing through this project. Also, as
of late 2018, XTE J1810-197 is again a radio magnetar after 10 years
dormant! Its chaotic rotation is better tracked in detail elsewhere,
but weekly observations with the UWL receiver are already providing
unique measurements of its radio spectrum and broad-band behaviour.
Our observations provide an important window into remarkably dynamic
magnetar magnetospheres, and characterise the conditions under which
radio emission takes place therein, placing constraints on the
emission mechanisms, which in at least some significant respects
differ from those of ordinary pulsars.
