General Description

• This is a program to optically charatecterize M stars that are being monitored
   for radial-velocity variations with CRIRES. One spectrum of each star should be
   taken in the non-standard setup centered at 830nm. This setup covers Halpha (6562AA)
   and the FeH molecular bands at 1mum, which are both essential to characterize the
   star's rotation and activity.
  
  Five of the six targets have short exposure times of a few minutes only. One object,
   SIP 1259-4436 is somewhat fainter, and the total exposure time of 2700s should be
   split into three exposures as given in the OBs.
  
  Usually, no flux is expected on the blue chip. Nevertheless, it should be included
   because in active M stars Hbeta may become visible. This is covered with the blue
   chip.
  
  If possible, the reduction pipeline should not be used with OPTIMAL EXTRACTION but
   in STANDARD mode. OPTIMAL sometimes fails at the low SNR level redward of 7000AA.
  If there is no way changing the extraction mode of the pipilen, of course, OPTIMAL
   is better than nothing.
  
  All targets are close low-mass stars with high proper motion. The position of the
   targets can be a few arcsec off the position in the finding charts. This is indicated
   in some cases in the finding charts and should not lead to confusion in any of the
   cases.
  
  happy observing!
