Abstract:
Doppler tomography of magnetic cataclysmic variables is a valuable
tool for the interpretation of the complex spectroscopic emission line
profiles observed for these systems.
We present the results of applying our inside-out velocity projection
and flux modulation mapping techniques to the Doppler tomography of
magnetic cataclysmic variables.
The inside-out projection reverses the standard velocity direction by
transposing the zero-velocity origin to the outer circumference and
the maximum velocities to the origin of the velocity space. The
inside-out tomogram is constructed by directly projecting
phase-resolved spectra onto the inside-out framework. In addition, our
flux modulation mapping technique extracts any information related to
the modulation of the line flux by utilising consecutive half-phase
tomograms. We apply this to both the standard and the inside-out
techniques.
Description:
doptomog is based on the fast maximum entropy Doppler tomography code
presented by Spruit (1998, astro-ph/9806141). The doptomog code can
construct tomograms independently in the standard and the inside-out
velocity coordinate frames.
