Two years of INTEGRAL monitoring of GRS 1915+105 Part 1: multiwavelength coverage with INTEGRAL, RXTE, and the Ryle radio Telescope

Understand

(Abridged) We report the results of monitoring observations of the Galactic microquasar GRS 1915+105 performed simultaneously with INTEGRAL and RXTE Ryle .

• We present the results of the whole \integral campaign, report the sources that are detected and their fluxes and identify the classes of variability in which GRS 1915+105 is found.
• The accretion ejection connections are studied in a model independent manner through the source light curves, hardness ratio, and color color diagrams.
• During a period of steady ``hard'' X-ray state (the so-called class chi) we observe a steady radio flux.
