Jeff mock supplied 6 different types of filters to use with the high resolution mode of the mock spectrometer. ... Plots were made of the time domain voltage response as well as the frequency domain power response. A decimation of 10 was used for the filter decimation. this gave a filter length of 80 coeff. The plots compare the filter shapes for these filter types (.ps) ( .pdf ) . ... Each color is a different filter type . middle: spectral density reponse for each filter . ...

XMM-Newton OM Response Files Page . ... Data Analysis SAS News What is SAS? ... The response files have the name om_effarea_<filter>_v2.0.rsp. The response files should be used in conjunction with a spectral data file containing the filter count rate. Such a data file may be created by editing the template filter file om_filter_default.pi with a fits editor such as 'fv' and changing the "RATE" and "STAT_ERR" entries in the SPECTRUM extension to the filter count rate and error. ...

. You can compare any two versions of a file that is under the control of SCCS with the sccsdiff command: /usr/sccs/sccsdiff -r version -r version s. filename . Using this command produces a line by line difference between the two versions of the file. Results are shown in the same format as that produced by the diff command. Examples .

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. ...
