Quiescent and Outburst X-ray Spin Profiles of GK Per
The energy-resolved X-ray spin profiles of GK Per. Data are from the 1995 February (quiescent) and 1996 March (outburst) ASCA observations folded on the spin period of 351 s.
The Y-axis in each of the 4 panels goes from 50% of the mean level to 150%. Note, in particular, that the spin pulse is very weak above 2 keV in quiescence.
