M. Cropper et K. Horne, MAPPING THE ACCRETION REGION IN AM HER SYSTEMS - ST LMI, Monthly Notices of the Royal Astronomical Society, 267(3), 1994, pp. 481-489
We have used the maximum entropy method to map the spatial extent of t
he X-ray and optical emission in the AM Her system ST LMi. The emissio
n region is arc-shaped with a core at one extremity in the X-ray map,
while the optical map is closely coincident but with some additional s
tructure.
