General Description

Optical spectroscopy of very low mass objects in the Coronet Cluster with
 FLAMES.

We are targeting a set of very low mass members of the Coronet cluster, aged 1 Myr,
 containing late-M type stars and BD. The stars have been detected via X ray and/or
 Spitzer surveys, and 2MASS and/or optical photometry has been checked to ensure
 relatively low extinction. The sample contains both stars with and without disks,
 and our aims are:
- To identify accretion examining the Halpha emission.
- To check youth via the Li I absorption at 6707 AA.
- To obtain spectra covering a large wavelength range that will allow us to get
 accurate spectral types for the objects.

Critical Observing Condition Constraints

There are no critical observing condition constraints besides the constraints
 listed in the "Constraint Set" of the OBs.

We would require clear weather (not necessarily photometric), a seeing up to 1.0,
 airmass up to 2.0, lunar illumination 0.8 at 60 degrees from object minimum.

Time-Critical Aspects

There are no time-critical aspects.

Special Execution Requirements

---(Empty)---

Special Calibration Information

No special calibration is required, besides the standard bias, flats and
 comparison lamps taken regularly with FLAMES during day time.

Given that we do not need an extremely accurate wavelength solution, the regular
 comparison lamps with the filters LR6, LR7 and LR8 are fine.
