Microquasars, with their complex interplay of accretion disks, relativistic jets, and coronae, emit across the electromagnetic spectrum. This talk will review the ongoing attempts to perform broadband, radio to gamma-ray, spectral decomposition in microquasars. I will summarise the key observables that help us distinguishing between different spectral models and physical components.
I will present an overview of broadband spectral data for microquasar systems, with a focus on black hole X-ray binaries. In particular, I will describe different broadband X-ray spectral data sets which are fitted to infer properties of the disk, corona, and/or jet, including e.g., the accretion geometry or black-hole spin. I will discuss the connection of X-ray spectra to other...
