General Description
OVERVIEW:
the aim of this part of the program to measure the radial velocity of individual
stars with V<18.5 in three differen regions of the Galactic globular cluster
NGC 6752:
(1)the central region
(2)a region around the millisecond pulsar MSP-E (about ~2.5" NE from the cluster
centre)
(3)a region around the millisecond pulsar MSP-B (about ~4.5" N from the cluster
centre)
The observations are organized in 6 OBs (2 for each pointing), each one lasting
less than 1h:
6752sinf_c1: 1st pointing in the centre
6752sinf_c2: 2nd pointing in the centre
6752sinf_e1: 1st pointing around MSP-E
6752sinf_e2: 2nd pointing around MSP-E
6752sinf_b1: 1st pointing around MSP-B
6752sinf_b2: 2nd pointing around MSP-B
NGS:
The NGS is the same for the centre and the MSP-E pointings. It is another star (0.5mag
brighter) for the MSP-B pointing.
Its R magnitude and distance from the FoV centre are the following:
pointing R dist["]
------------------------
centre 12 3.4
MSP-E 12 1.6
MSP-B 11.5 1.8
BRIGHTEST STARS:
As apparent from the finding charts, the brightest stars situation is the following:
pointing
---------------------------------------------------------------------------------------
centre no bright stars
MSP-E only the NGS (V~12.7, K~9.7) is at the east-side border on the SINFONI
FoV
MSP-B only the NGS (V~12.1, K~9.1) is at the east-side border on the SINFONI
FoV
NOTES:
+ When choosing the telescope Guide Probe, please be aware that during the science
template ("FixedSkyOffset") the SKY position will be taken about 2.4' north and
30" west
from the science target. If possible, we would prefer a unique GP for both sky
and
target position.
+ During the acquisition of the NGS, before closing the loop, there is no need
to take sky because the surrounding fields are still too crowded to get a
reliable estimate of the background.
+ Once the NGS has been acquired and the loop is closed, no need to center
the target since we provided very accurate coordinates. Moreover, the target
coordinates correspond to the cluster C_grav(6752sinf_c1,c2), and the nominal
position of 2 MSPs (6752sinf_b1,b2,e1,e2), so not to specific visible sources.
+ Since it's a very crowded field you might want to reduce the size of the MACAO
diaphragm in order to maintain the loop closed on the NGS.

Pre-imaging sources not listed above
Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
Did you indicate the magnitude of the brightest object in the field in
each SINFONI OB?
If you are using the AO: Did you indicate for every OB the magnitude
of the guide star, and its distance to the target (if any)?
If you submitted OBs for standard stars, did you use the provided StandardStar
templates?
If you are using a specific offset pattern or position angle: did you
check carefully the definition in the manual?
Did you make really sure that none of your OBs ever saturates the detector?
If you are using the AO: did you enter the correct Strehl Ratio (on-axis,
K-band) AND the seeing value in the constraint set?
