General Description

SINFONI IFU observations of a highly magnified, gravitationally lensed
 galaxy at z=3.072.
We are mapping OII(3727), Hbeta(4861) and OIII(4959) which are redsifted to 1.51um,
 1.97um and 2.04um respectively.  We are using the H+K grating. 

We are using the LGS with the 3x3" field of view (sampled at 0.1"x0.1").  There
 is a tip-tilt star (magnitude R=14.8, B=16.1, K=12.7) aprox 27" away.

Acquisition:  The target is K~17.5(Vega) and so acquisition is direct.  The target
 is extended, and fills the IFU, so please center the IFU as carefully as possible
 (see finders). 
Using the ITC, we expect that a 40second (sky-subtracted) image acquisition will
 reach a S/N~5 per pixel - sufficient to center the IFU.

Since the target is extended, we are chopping by dec=+7" to sky to for sky-subtraction.

The finders show the target, Tip/Tilt star, and Guide star.  Finders are made using
 a DSS image, HST I-band image and Keck/NIRC K-band image.

We do not require any special calibrations for this run - the night-time flats/arcs/standards
 will do.

We already have a strong detection of OIII(5007) emission form a (seeing limited)
 longslit spectrum with  Keck/NISRSPEC in 30mins.  The target comprises a foreground
 elliptical galaxy which is lensing the background (high redshift) galaxy.  We expect
 to be able to see line emission from the lensed galaxy with SINFONI after 1 complete
 OB from the target.  We also expect to detect continuum emission from the foreground
 elliptical galaxy in each OB - although this might be weaker.
