General Description

This is an imaging run to probe the inner structure of the circumstellar
 envelope of V Hya.

- Coronographic imaging mode of NACO , using the 4QPM coronograph,  will be used
to perform high dynamic diffraction-limited observation of V Hya in the near-infrared.

- L Imaging will be done using the narrow-band filter NB3.74 to avoid detector saturation.

Waiver Requests

A Waiver request (WaiverID:  078.D-0507A.01) was submitted to switch from
 H, Ks, L', and M' imaging to IB_2.15
4QPM coronography plus L (NB 3_74) imaging in our NACO Run  0878.D-0507(A). 

Our Waiver request was approved

Critical Observing Condition Constraints

- Good seeing is needed for the coronographic observations 
- In each mode Scientific object and its corresponding PSF have to be observed in
 the same conditions
in the same night
 - Observations in IB215 (Object + PSF) and NB3.74 (Object + PSF) could be made
 at different dates

Time-Critical Aspects

Special Execution Requirements

In each mode (coronographic and Imaging) Object and its corresponding
 PSF have to be observed in the same conditions and in the same night
