/**
 * 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://www.mathworks.com/matlabcentral/fileexchange/37103-avantes-to-matlab>
 * 
 * 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.
 * 
 * Written and tested by Filip Dominec, 2017-2018
