Swift XRT observation of 1A 0535+262
Abstract
The current giant outburst of the Be X-ray pulsar binary 1A 0535+262 (ATel #2324, #2336, #2337) was observed by Swift/XRT in windowed timing mode for 1ks on 2009-12-08. As the raw spectrum is piled-up with a count rate of 250 -- 300 ct/s, a circle with a radius of 10 pixels centered at the source position was excluded during spectral extraction. A background spectrum was extracted from a neighbouring region.
