Ulysses data obtained at high solar latitudes during periods of minimum activity in 1994 and 2007 are examined to determine the relation between velocity structures called microstreams folds magnetic field switchbacks. A correlation is found. The possibility peaks originating from coronal X-ray jets re-examined; we now suggest that consequence alternation patches switchbacks quiet periods, wher...

Device characterization typically involves generating one or more targets each comprising a number of color patches and making colorimetric measurements of these patches. In order to derive the characterization function, one has to obtain the correspondence between the set of colorimetric measurements and a set of device signals. In the case of output device characterization, the device signals...
