General Description

This run consists of JHK imaging of 3 young open galactic clusters. The
 run is aimed at obtaining near-infrared photometry of all the stars observed with
 VIMOS/MOS (run B).  
The observations consist of short standard jittered exposures at four different
 positions (coincident with the VIMOS quadrants). For each cluster 4 OB are requested.

Given the presence of bright stars in the fields (brighter than J=9.3, H=9.6 &
 K=8.6 mag) a waiver was requested. The waiver was (conditionally) approved. 
Following the advices of USD, the DIT adopted is the minimum DIT (1.3 sec). 
The number of OB per cluster is the minimum possible to fulfill the science case.
 
To lower the risk of saturation the seeing constraint was relaxed compared to what
 requested in phase 1 (1.4 instead of 1.0).

One of the conditions specified in the waiver is that these observations will be
 executed only at the end of the night or before the instrument is changed. In this
 regard, please consider that the clusters are observable at the end of the night
 ONLY in the first half of P81 (April-June).

Waiver Requests

Due to the presence of bright stars in the requested fields a waiver (081.C-0208D.01.WAV)
 was submitted. The waiver was conditionally approved (see \"General Description\").
