  %LSMCHANNELWAVELENGTH Class representation of ChannelWavelength in LSM files
  %   For images acquired with the meta detector the wavelength range for the
  % detected emission light is known. The information is stored in a block in
  % the image file. The u32OffsetChannelWavelength entry of the CZ-Private 
  % tag contains the offset to this block.
