General Description

This is a "visual" binary orbit observing program for one M dwarf binary
 with an
excellent double-lined spectroscopic orbit, expected to produce masses (and a
distance) with sub-% accuracy. 

Important note: the brightest star in the field, specially in the visible, is
Gl570A (V=5.72), and NOT Gl570B (V=8.01). Component A is 25" away, to the SE
of B.

Critical Observing Condition Constraints

The baselines should preferably be short because the maximum
separation is large by AMBER standards (about 0.25") and the system is never
very tight.  The exact baseline configuration does not matter and up to 80m or so
 
is fine.

Time-Critical Aspects

The orbital period is approximately 10 months,
so for good phase coverage the various observing runs (ABCD) should be spaced 
as much as compatible with observability and scheduling contraints. Once a month
or so is fine, and wider spacing is better. Run E is for a different target with
a much shorter period and has independent constraints.
