Doppler
Tomograms of Disks
€Using phase-resolved spectra (corresponding to different views of the system) the emission from the different
emission regions can be mapped (similar to medical
tomograms)
€The location of the impact region can also be seen in
Doppler tomograms
€Since highest velocities in disks are at the centre and
lower velocities outwards, the maps need to be ³inverted² in
the transformation to spatial coordinates for the disk
component
