      <Description>The Level 1C limb data is sampled on a uniform angular grid  Latitude. 
	  The data is resampled as follows:
		* About 4 scan mirror positions to fill the 0.2° L1C bin.
		* Narrow slit width: 0.075°
		* Use center of L1B and L1C bins to resample (nearest neighbor) GOLD Public Science Data Products Guide (1.0) 26
		* Spectral data is combined within a L1C bin WITHOUT doing any wavelength alignment
		for each L1B sample
		* 30 bins Altitude
		* 32 bins N-S  </Description>
