Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...

... After the best fit is obtained, the confidence limits on two parameters can be obtained by running search_grid . This task calculates a grid of values for a given input model. ... Then search_grid will select the last dataset used (from pkgpars ), will use the best fit from the last run of fit (the null string ``'' at the model prompt will always select the best fit from the _prd.tab file), and will place the results in a _grd.tab file with the same root as the observed file. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
