... If the measuring aperture varies, a varying amount of starlight will be excluded. Furthermore, the excluded fraction is wavelength-dependent; so the transformation from instrumental to standard system changes. ... Unfortunately, sometimes it is necessary to combine measurements made with different field stops. Observers should realize that this really means different instruments; the differences are usually several per cent. ... Usually, the actual aperture sizes are only approximately known. ...

The HyperNews Linux KHG Discussion Pages . ... Keywords: scheduler overhead . ... From: Jasleen Kaur < jks@cs.utexas.edu > . Hi, I am implementing a different scheduling policy in the scheduler of Linux 2.0.0. I need to measure the time taken for choosing the next task to be scheduled, i.e., the actual time spent in the schedule() function, without the actual context switch having taken place. Since I clear interrupts in schedule(), how do I measure the time? ... Thanks, Jasleen Kaur . ...
