General Description
We will perform high-resplution near-infrared imaging of selected clusters
of pre-main sequence (PMS) stars, as they have been classified with Hubble/ACS imaging
in the optical, in a star forming region, named LH 95, of the Large Magellanic Cloud
(LMC). The aim of this observing run is to perform an original NIR characterization
of this PMS population, that will allow a comprehensive study of the most recent
low-mass star formation and the low-mass Initial Mass Function in the LMC. Our observing
strategy is to perform NAOS/CONICA Imaging in the Ks, H, J bands with the S27 camera
(28 x 28 arcsec) of the star forming association LH 95 (system) and three peripheral
compact sub-clusters in its vicinity (cluster1, 2 and 3). For the brightest source
of one of the targets (cluster1) there is evidence of high H_alpha excess, and SINFONI
spectroscopy has been performed during Period 78 (run 078.D-0200(A)). These data,
which are currently under reduction, will be a unique spectroscopic and photometric
set of NIR data of a candidate AeBe Herbig star and its surrounding cluster in the
low-metallicity environment of the LMC. Therefore, we set in our Observing Blocks
the highest priority for the observations of the SYSTEM and CLUSTER1. In the following
we provide magnitudes for the brightest sources and the reference stars for every
required FOV: 1) System: Brightest Star: K~14.08 mag, Reference Star: K~14.51 mag.
2) Cluster 1: Brightest Star (it is the Reference Star): K~14.57 mag. 3) Cluster
2: Brightest Star: K~13.82 mag, Reference Star: K~14.93 mag. 4) Cluster 3: Brightest
Star (it is the Reference Star): K~13.71 mag.

Pre-imaging Requirements
Source(s) of Pre-imaging
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 ?
If you have PSF reference star OBs, do the names of those OBs begin with
PSF_ ?
If there are Finding Charts attached to your OBs, is the field-of-view
of at least one of these charts 2' x 2' (with clearly labelled field orientation)
?
Have you clearly marked and labelled your wavefront reference objects
R1, R2, R3, ... (as specified in the NAOS Preparation Software) on your Finding
Charts ?
Have you specified the magnitude of the brightest object in the field-of-view
for each OB ?
Are there objects in any of your fields (including standard stars) which
are brighter than the limits specified in the User Manual and on NACO web Pages
?
If the previous answer is yes, have you given a list of OBs and a justification
for the brightness limit violation in the general description field ?
