This is a straightforward LSS programme, with only one OB. The target
is PKS2351-154, which is a high-redshift quasar showing dramatic
fluctuations in the X-ray flux. The aim of the project is to study the
probable high-redshift warm absorber which should be located in the
local environment of the active nucleus.  

The same OB takes 2x750sec spectra without order sorter and 2x750sec spectra
with order sorter filter. When obtaining the calibrations, remember to
take them for both configurations.

This OB has to be executed in coordination with XMM observations.
The XMM schedule is not known yet. But the PI will communicate it
to us 4 weeks in advance. For this reason the OB should be kept on-hold,
until USG gives the green light.
