A0_superfine grid position errors

    A superfine grid was started 21jun10 on position A0, focus=0 with .37 amin steps (31x31 points).The source J1330+251 was tracked.  The postioning code  used rick fischer's computation that iterated to find the correct offset position for the telescope.
The 1st plots shows the az,za covered as well as the changes to the offsets from rick's code (.ps) (.pdf)

• az,za covered
• the standard positions visited in the grid (black) as well as the new offsets (blue)
• The offset differences for the two methods.
