General Description

• The program consists of UVES observations of the metal-poor star HE1405-0822,
  which shows an enhancement of r- and s-process elements. The aim is to carry
  out an abundance analysis and constrain the origin of the neutron-capture 
  elements in this class of stars, of which so far only three examples are known.
  
  We want to use Dichroic 1 with central wavelengths 346nm in the blue arm and
  580nm in the red arm. A slit width of 0.8'' will yield R=50,000. We aim at 
  reaching S/N=150 per rebinned pixel at 380nm, where two important Gd lines are
  located (at 376.84nm and 379.64nm), and S/N=110 at Ir I 351.3nm. 1x1 pixel
  binning is used because we are not readout-noise limited. The spectra will later
  be rebinned.
  
  The slit shall be put to parallactic angle, and the derotator mode is set to 
  "ELEV" in order to avoid slit losses. To facilitate cosmic ray removal, and to 
  allow for flexible scheduling, the total exposure time is split into 5 exposures
  of 50 minutes each.
  
  Because the star is relatively bright (V=14), the constraints on the observing
  conditions are low; i.e., the observations can be done in bright time, at a 
  seeing of 1.2'' and during the presence of thin cirrus.
