This project aims to make maps at 100 positions in a 10 x 10 grid.
Each position has been given its own "source" name in the database:
UD##XXXX, where ## indicates the wobbler throw that should be used
for that position (either 36 or 48) and XXXX indicates its location
in the 10 x 10 grid (e.g., UD48+5+5).

The following figure shows all 100 positions in the field. "Sources" 
that have already been observed show mini-maps indicating the directions
of their subscans (thin lines). "Sources" that have not yet been observed 
still show the numbers that are part of their names.

If you are about to start a new map for project 217-07, 

(1) Note the current LST.

(2) Determine the approximate subscan direction that will result for
a map starting at the current LST, by referring to the figure *below*.

(3) Find a high-priority position in the figure *above* whose 
neighbors have been mapped (if at all) with different subscan 
directions from a map starting at the current LST.  (Neighbors 
with perpendicular subscan directions are ideal.)

(4) Determine the "source" name for this position: UD + wobbler 
throw (from top of column) + grid position (from cell). This is 
the "source" you should map following the instructions in the 
obsform.

The Co-PIs will try to update the top figure on a daily basis, but 
in case we miss a day you should still check on the project page 
in the database that the "source" you have chosen has not already
been observed.  If you have questions, contact us at 
ajbaker@physics.rutgers.edu and omont@iap.fr. We thank you in advance 
for your hard work!
