Parkes observations for project P554 semester 2006OCTS

We ask to perform a full transit observation, starting at UT 17:00 on
the day 06 March 2007, of the anomalous X-ray pulsar XTE J1810-197,
which has been recently discovered to emit pulsed radio
emission. Since a XMM observation of the same target has been secured to us
for the same day (starting at UT 16:00), the requested slot will allow
us to collect about 9 hours of simultaneous X-ray and radio data. The
requested coordinated X-ray/radio observation will significantly
contribute to shed light on many still unanswered questions about this
intriguing source. In particular, it will pose constraints on the
extension of the radio and X-ray emitting region(s), it will allow to
study pulse shape and pulse fraction variations over more than seven
orders of magnitude in frequency and it will provide the database for
the first detailed broad band spectroscopy analysis of the source.
