Parkes observations for project P554 semester 2006OCTS

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