Hi David, Scott and Doug,

	I've visually inspected the spectra in plate 306, which David
	certified to have reached the desired S/N.
	This plate can be used as a "truth table" for any 1d pipeline
	we write.
	Please find below the spectro1d output, and my notes:
	The format is

	1) fiber #, 
	2) redshift assigned by spectro-1d,
	3) z_status
	4) spectral classification
		The last 2 are enumerated types, please look at
	http://www.sdss.jhu.edu/sx/sxqt/specClasses.html
	for their values.

	5) my notes in the foll. notation

		G = galaxy with correct 1d redshift
		G? = galaxy with questionable redshift
		Q (?) = quasar with correct (questionable) redshift
		S = star, usually followed by its spectral type
		
	There were some very interesting objects in this plate, including
	a CV and a few BAL quasars.

	Cheers,
	-- Vijay
