An example: first integral can correspond to the profile of active region and second integral can correspond to the profile of quiet chromospheric region. ... The second profile (which is subtracted from the first one) you extract after clicking on "SUBTRACT"-"MARK QUIET PROFILE" and marking the region. ...

Summary of SPHERE performance at NIH Ralf Siebenmorgen (PS) and Markus Kasper (PM) SPHERE performs in the NIH similar to what was achieved in Grenoble. ... IRDIS The IR and V filters are well mounted and the positioning accuracy is within a 1% pixel tolerance. ... The IRDIS detectors have a read-out noise 9.4 e-, a gain of 2e-/ADU and the dark current is <0.5e-/pixel/s. The instrumental background is still high. ... Centering of the pupil is achieved at an accuracy of 0.1% of the pupil diameter. ...
