See here (UVEX spectra processing) and here (eShel spectra processing) for tutorials.Īdd a powerful tool for convert file name of sequence of images or individual image : Mics tab -> rename tab and drop the file into the zone for convert in the working directory.Īdd off CMED algorithm (for CMOS camera).
See for example tools for compute limit magnitude of a spectrograph here. Check 'Optimal binning' option for normal work : This new possibility is practical to manually and easily re-center a spectrum sequence with respect to a reference spectrum (the current spectrum) :dd the choice of binning method for computing eShel spectra ('Instruments' tab).
New important functions for eShel user's. ISIS DRAW 2.5 WINDOWS 10 KEYGEN ISIS DRAW 2.5 WINDOWS 10 KEYGEN. Seeīug corrections + add median filtering option for eShel users (WARNING and IMPORTANT: applicable only if the spectrum is correctly sampled i.e. For undersampled spectra, unselect median filtering option of course and the "Optimal binning" option (improved). Tips: I suggest the binning 1x1 mode during acquisition of eShel spectra for an optimal sampling (possibility to exploit the efficiency of median filter for increase SNR) and pseudo noise reduction.Īlso, more option for VHIRES spectra processing and more.įix a Base 0 vs Base 1 problem concerning data values when computing a polynomial dispersion equation with the "Dispersion" function of the "Profile" tab :Īdd of a "Save" button in the command "Comparison" dialog box accessible from the "Profile" tab. By clicking on this button you modify the compared spectral file shifted by the "-shift" value along the spectral axis.
