...regions
This case well describes the magnetically controlled accretion in highly magnetised CVs where a strong spin-orbit torque is expected to take place forcing the binary system to rotate at the spin period of the WD. Depending on the magnetic field strength, synchronous or asynchronous systems can originate (see §1.1.3).

...flow
Depending on how the matter attaches itself to the field line, the accretion column could be a ``hallow'' rather than a filled cylinder.

...process
The process to alternate electron capture and beta decay of the same nucleus without generate energy but with only release of neutrinos is called URCA process. Specifically a neutrino-antineutrino pair is produced with no change of composition, but neutrinos run off with energy provided by thermal environment.

...(PSPCs)
One of the two PSPCs was lost on 1991 Jan. 25 during an almost fatal on board computer glitch which caused the spacecraft to start spinning in an uncontrolled manner for about 15 hr. During this interval one of the two PSPCs performed a ``Sun slew'' which destroyed the detector window.

HRI observation were also wobbled in order to smooth out quantum-efficiency variations in the microchannel-plate detector.

This is unlike the derivation of the detection threshold 359#359 which requires a detailed knowledge of the pdf for higher values, given the usually high number of 360#360.

...verified
Is important to stress out here that the presence of side lobes around a coherent signal, due to the presence of periodic gaps in the sampled time series, can be regarded as a particular case of statistical correlation which involves only some periodically distributed Fourier frequencies.

For this reason the associated spurious signal changes as one varies the binning time allowing to distinguish between spurious and source intrinsic signals.
