Default = 64. (0=default) 64 Include data for transmitter gates? 1=yes, 0=no 0 Include data for noise gates? 1=yes, 0=no 0 File/tape that contains raw records to read /dev/rmt/0hb Extra info: mode: mode 1 computes first 3 moments for the selected receiver S/N (|S+N| - |N|mean)/(|N|mean) (noise computed from noise gates), mean doppler (corrects if double pulse), spectral width (|S+N| - |N|mean) >? 0.5 (|S+N|max - |N|mean) mode 2 computes spectra for chosen receiver if double pulse will save complex spectra for rx gates mode 3 computes spectra for chosen receiver and cross-coherence with other rx's using chosen receiver as reference. first range: last range: to process all useful ranges set first range to 0 and last range to at least -2*range_step in kms Computation of noise: After several runs over data it seems that the minimum of noise power in noise gates appears to be the ideal choice for determining noise power level. A percentile routine is used that sorts the bins in ascending order, The 75th percentile bin is chosen, for 64 pnts that would be bin 48. File name specification: On the mac filenames should be specified relative to the current directory (:) if data is to be read from a file 'datafile' in the subdirectory 'data', it would be specified as ':data:datafile'. Following is a simple filename tree to use as reference: Diretory Tree mumparms Name relative to current directory HardDisk :C++7.0:Development:Projects:Raw:mumparms | ... -------------- ... | C++7.0 :Development:Projects:Raw:mumparms | Development :Projects:Raw:mumparms | ... -------------- ... | Projects :Raw:mumparms | ... -------------- ... | | Raw Proc from Raw: from Proc: | | mumparms ::Raw:mumparms ------------- ----------------- | | | | mumparms moments plotmoments misc | ... -------------- ... | from tmp: tmp ::::Raw:mumparms
