General Description

This is a simple K- and L-band imaging of embedded protostars with NAOS-CONICA
 to search for close (sub-arcsecond) companions.

Each OB contains an acquisition template and a single science template. K- and L-band
 observations of the same target represent 2 OBs because of the different IR WFS
 configuration.

Once the acquisition image has been obtained, please make sure that the DIT value
 in the science template is such that the peak intensity level for the 
target is on order 1/3 to 1/2 the detector linearity level, so as to ensure a good
 enough sensitivity to companions. In all OBs, DIT has been set for the acquisition
 template to half the value used in the science template, to be on the safe side.

NB: the K-band magnitudes of the targets indicated in the AO configuration files
 are artificially 1.5 mag fainter than their actual value. This is to compensate
 for the extremely red (J-K > 5 mag in most cases) colors of these objects, which
 cannot be represented by M0 photospheres, and has been taken into account while
 estimating DIT. This offset is not present for the OBs where guiding is performed
 off-axis (EC89, EC95 and EC103), for which the guide star is a normal-color star.

Critical Observing Condition Constraints

No critical observing conditions besides the usual airmass, seeing and
 transparency conditions listed in the OB constraint sets.

Time-Critical Aspects

No time-critical aspect for this project. OBs can be run in any order
 within the priority order selected in the OBs. In short, all the L-band OBs are
 priority 1 and the K-band OBs are priority 2. In this mode, we increase our chances
 of observing all objects in at least one filter.
