Abstract for MTS:
FORS2 MXU spectroscopy of z=3.1 protocluster. Because of the faintness of the targets, the same mask is observed for the 9 hours of allocated time. The mask targets 32 candidate high redshift galaxies. In addition, 8 (bright) stars are placed in the mask (using boxes with sizes 3"x3"-4"x4") to check the centering of the mask in the through slit image.
To prepare the mask, an I band image taken with FORS2 in September 2002 was used.
For the image acquisition, 10 reference stars were selected with (Vega) magnitudes in the I band in the range 18-21.8. On the finding charts these alignment stars can be recognized by the square slit through which they are observed.
Waiver Requests
===============
A change of observing strategy was approved by Dr F. Primas (USD head): change from bright time to grey time, while using only half of the allocated time - 9 hours instead of 18 hours.
