Monitoring of variable sources, notably X-ray binaries, at 15 GHz

The Ryle Telescope is used from time to time for monitoring variable sources, including GRS 1915+105, Cygnus X-1 and Cygnus X-3.

The basic parameters of the system are described in Pooley & Fender (1997, MNRAS, 292, 925-933). In order to make the data available for other observers to assess the current state of the system, some files (in gzipped postscript format) are available for GRS1915+105, Cygnus X-1, Cygnus X-3 and for J1118+480 (on a "best efforts" basis) for consultation.

Many of these plots also include data from the RXTE All-sky monitor which are gratefully acknowledged.

There is also a table of data on GRB021004
