g0mastr8.dxf.gz		Gnu-zipped Autocad R12 .dxf
	This is the latest version, version 8, of the master drawing, uploaded
	on May 1, 1997.  The drawing has been cleaned up and updated.  Also,
	a set of notes is now included to explain certain features of the draw
	ings. For example, we have always said that all of the components in
	G0MASTR are drawn at their operating temperature, and for the locations
	of most features this is true.   However, all standard plate thicknesses
	are shown at their nominal room temperature thickness no matter what 
	their operating temperature, as are all fasteners, bolt holes, and LHE
	and LN2 pipe sizes.  To really make G0MASTR reflect true operating 
	temperature conditions all of these sizes would have to be corrected for
	thermal contraction.  Another point:  While the spectrometer will be 
	built to English standards G0MASTR is currently metric.  A further
	note:  Many items in this drawing are not up-to-date.
