|
| 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. |
