We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...

... The first is the pointing accuracy of the FOC. The second is the internal geometric accuracy of an FOC image itself, including the correctness of the distortion model, the plate scale, and the image rotation. ... The accuracy with which HST places a target in the FOC field of view depends in a complex way on the target coordinate uncertainty, the positions of the guide stars in the FGS fields of view, and the alignment of the FOC imaging aperture with respect to the FGS reference frame. ...

With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...

... I am developing an Informed Prefetching and Caching system as part of the kernel in which it is very important that the memory assigned to hold the data does not get swapped to disk. Without any thought to swapping I used vmalloc() to assign memory to the data structures of the Informed prefetching system. ... I later realized that most probably the pages assigned using vmalloc() were getting swapped to the disk and when I referenced them, they were brought from the disk rather than memory. ...

Herman Cortes technology Projects German and I had a long talk yesterday about his work with the focal phase arrays and the other task he's engaged with, designing an extremely broadband feed that is compact and can be fabricated inexpensively. He's been making good progress with both by assigning Eliana to do the initial work with the focal phase array, and he himself has been concentrating on the broadband feed design. ... While still in progress, Eliana's work will surely succeed. ...
