General Description

We are using VIMOS to image the high redshift cluster MS1054 in the U-band
 at 2 different pointings. 
Exposures are taken at 5 offset positions for each pointing.

Waiver Requests

A waiver request for having OBs of 1.2 hr duration was submitted on July
 22 and approved on July 28.

Details of waiver request:

>We kindly request a waiver for submitting 2 OBs of 1.2h duration each. 
>We got 2.4h of service mode imaging with VIMOS allocated. The standard 
>requirement of 1h OBs would render the 3rd OB of 0.4h practically 
>useless due to the overhead (telescope preset = 6 min + imaging 
>acquisition = 3 min is already 9 min out of 24 min allocated for the 3rd 
>OB if OBs would be 1 hr). Having just 2 OBs of 1.2h each would maximize 
>the efficiency of these observations. We will accept that the observing 
>conditions will be solely determined based on the first hour of each OB, 
>rather than the entire 1.2h.
