srcut: synchrotron spectrum, cutoff power law
srcut describes the synchrotron spectrum from an exponentially cut off
power-law distribution of electrons in a homogeneous magnetic
field. This spectrum is itself a power-law, rolling off more slowly
than exponential in photon energies. Though more realistic than a
power-law, it is highly oversimplified, but does give the maximally
curved physically plausible spectrum and can be used to set limits on
maximum accelerated-electron energies even in remnants whose X-rays
are thermal. See Reynolds & Keohane
(1999)
and Reynolds (1998). Note that the radio spectral
index and flux can be obtained from Green's Catalogue for galactic SNRs.
