General Description

SINFONI IFU observations of high redshift galaxies. In all cases, we
are peaking up on nearby stars and applying blind offsets to the target. The offsets
for each galaxy are given below. I have tried to add as much detail as possible
in the notes below.

-------------------------------------------------------------------------------------------------------------------------------------

MACSJ2135-0102:

This is a SINFONI IFU observation of a high-z lensed galaxy. We are using the 8x8"
field of view and the H+K filter. This observation also uses AO+NGS using a R=10.4
(B-R=0.1) star approximately 55" from the science target.

Acquisition:
Standard NGS acquisition: peak up on the bright star (please center as carefully
as possible). The telescope should then be offset to the science target. (For
information, the offsets FROM the NGS (peak-up) star TO the target are: dRA = 38.19"
East and dDec = 42.52" South).

For information:

The NGS (peak-up) star is at:
RA = 21:35:09.141
Dec = -01:02:10.59 (J2000)

The science target is at:
RA = 21:35:11.689
Dec = -01:02:53.11

For reference, the offsets FROM the NGS (peak-up) star TO the target should be:
dRA = 38.19" EAST
dDec = 42.52" South

The target is spatially extended, but with the 8x8" field of view we can nod within
the field and so the 'sky' exposure is dDec = 1.8" North and dRA = 0" EAST.

I have attached 2 finders: 1 made using ground based K-band imaging and another
made using HST I-band imaging.

--------------------------------------------------------------------------------------------------------------------------------------

MACSJ1347-11:

This galaxy is at z=1.78 and we are using the 3x3" field of view of SINFONI and
mapping the H-alpha emission line in the H-band. This is an NGS+AO observation
using a R=16.7 star which is 9" from the target.

MACSJ1347-11 Acquisition:
-------------------------

The target is faint, so we will peak up on a bright star (which is also the NGS
star) and then blind offset.

The co-ords of the (NGS) peak up star are:
RA: 13:47:28.60
Dec: -11:45:36.99 The peak-up star is H=15.2 mags (Vega)

The science target co-ordinates (defined as 'Target' in the OB are:
RA: 13:47:29.186
Dec: -11:45:38.320

for reference, the offset FROM the peak-up star TO the target should therefore be:
dRA: 8.52" EAST
dDec: 1.33" SOUTH

after this move, the we assume that this position is now (0,0).

The target is spatially extended, so we are using ABC sequences to cover the galaxy
(A=target1, B=sky, C=target2).
Position A (Target1) is at: (0,0)
Position B (sky) is at: (0,-10)
Position C (target2) is at: (2.3, -2.1)
This is defined in the observing sequence in the OB.

-------------------------------------------------------------------------------------------------------------------------------------

MACSJ0451+0006

This galaxy is at z=2.005 and we are mapping the OIII(5007) and Hbeta(4868) emission
in the H-band. This is a non-AO observation

MACSJ0451+0006 Aquisition
-------------------------

The target is faint, so we will peak up on a nearby star and apply a blind offset.
The peak-up star (defined at 'Target' in the OB) is at:
RA: 04:51:53.165
Dec: 00:07:11.730 H=12.2 magnitude (Vega)

Offset FROM peak-up star TO target:
dRA: 63.81" EAST
dDec: 50.71" SOUTH

We are using the 8x8" field of view. The target is spatially extended, but can
still be chopped within the IFU field of view for sky subtraction. We are therefore
using ABBA sequences and a chop of 4" East for the sky position.

-------------------------------------------------------------------------------------------------------------------------------------

A1835
-----

This galaxy is at z=2.07 and we are targetting H-alpha, H-beta and OIII. This is
an AO observation using an R=16.3 mag star (B-R=0) approx 50" away. We appreciate
that at this distance, the correction will only be marginal.

A1835 Acquisition
-----------------

The target is faint, so we peak up on the nearby NGS star and apply an offset.

Co-ordinates of the peak-up star are:
RA: 14:01:01.462
Dec: 02:51:29.74 H=15.1 mags (Vega)

The co-ordinates of the science target are:
RA: 14:01:00.077
Dec: 02:52:22.100

for reference, the offsets FROM the peak-up star TO the target should be:
dRA: 7.26" WEST
dDec: 52.36" NORTH

This places the IFU on the target galaxy. We will use the 8x8" field of view and
chop the galaxy within the IFU.

-------------------------------------------------------------------------------------------------------------------------------------

A1689
-----

This galaxy is at z=3.05 and we are mapping the OIII and Hbeta redshifted into the
H-band. This is a non-AO observation.

Acquisition
-----------

The target galaxy is faint, and so we peak up on a nearby bright object and apply
a blind offset.

The peak-up star (defined as 'Target' in the OB) is:
RA: 13:11:26.243
Dec: -01:19:56.47

The offsets FROM the peak-up-star TO the target are:
dRA: 2.41" EAST
dDec: 0.48" SOUTH

This places the target galaxy in the middle of the IFU. We will chop by 8" east
to sky for sky-subtraction and use ABBA sequences.

Time-Critical Aspects

If at all possible, please observe one (or more) of the OBs from MACS2135-0102
 as soon as possible (before mid june if possible).  We are writing a nature paper
 on the discovery of this galaxy, and would like to include a near-IR spectrum (we
 will then publish the whole sinfoni dataset/analysis at a later date).

Special Execution Requirements

Please note that in all observations, acquisition is carried out by first
 acquiring a peak-up star and then applying a blind offset to target (see notes for
 the offsets).
