Broad-band X-ray observations can provide limited temperature diagnostics through filter ratios. A high cadence observation of an active region made with a single Hinode/XRT filter allows us to use an alternative approach in which we measure the time fluctuations of the pixel count rate and use the variance as temperature proxy. We show the results and discuss limitations of method.

Abstract
Broad-band X-ray observations can provide limited temperature diagnostics through filter ratios. A high cadence observation of an active region made with a single Hinode/XRT filter allows us to use an alternative approach in which we measure the time fluctuations of the pixel count rate and use the variance as temperature proxy. We show the results and discuss limitations of method.File in questo prodotto:
