Notes
1) One SEGUE-faint plate equals two plate-equivalents
2) For this accounting, # of tiles is computed by dividing the total number of actual plates observed by two.  
A SEGUE  tile is considered complete when both the bright and faint combination for a field are complete.
3) 2006-Q2 progress includes data collected through 07/06/06
