- """Avantes USB spectrometers are supplied with a Windows binary which
- generates one ROH and one RCM file when the user clicks "Save
- experiment". In the version of 6.0, the ROH file contains a header
- of 22 four-byte floats, then the spectrum as a float array and a
- footer of 3 floats. The first and last pixel numbers are specified in the
- header and determine the (length+1) of the spectral data. In the tested
- files, the length is (2032-211-1)=1820 pixels, but Kaitai determines this
- automatically anyway.
-
- The wavelength calibration is stored as a polynomial with coefficients
- of 'wlintercept', 'wlx1', ... 'wlx4', the argument of which is the
- (pixel number + 1), as found out by comparing with the original
- Avantes converted data files. There is no intensity calibration saved,
- but it is recommended to do it in your program - the CCD in the spectrometer
- is so uneven that one should prepare exact pixel-to-pixel calibration curves
- to get reasonable spectral results.
-
- The rest of the header floats is not known to the author. Note that the
- newer version of Avantes software has a different format, see also
- https://kr.mathworks.com/examples/matlab/community/20341-reading-spectra-from-avantes-binary-files-demonstration
-
- The RCM file contains the user-specified comment, so it may be useful
- for automatic conversion of data. You may wish to divide the spectra by
- the integration time before comparing them.
