General Description

• J-band spectroscopy of 3 L-dwarf candidates in Taurus:
  ------------------------------------------------------
  
  The 3 objects are named CAHA1, CAHA2, CAHA3. As they have different 
  J-band magnitudes the 5.0 hours telescope time is distributed among them according
   to
  their brightness. In the following each objects and its properties and important
   
  observing information are shortly summarized. 
  
  The slit width is for all objects 0.8 arcsec.
  
  
  1) CAHA1:
  -------------------
  RA (J2000): 04 36 09.04
  DEC (2000): 24 08 21.2
  J-band: 16.8 magnitudes
  
  Acquisition Reference star: none
  Slit orientation: 71.34 degrees from north to east
  
  The slit orientation was chosen in a way to put a second star in the slit (see FC).
  Please center the slit ON the science target.
  
  2 OBs: CAHA1-A, CAHA1-B (41 min 46 s each)
  The OBs are identical! The constraints on the OB length required to split the total
   time in two OBs.
  
  
  
  2) CAHA2:
  -------------------
  RA (J2000): 04 39 47.16
  DEC (2000): 25 53 32.2
  J-band: 16.3 magnitudes
  
  Acquisition Reference star: none
  Slit orientation: -6.44 degrees from north to east
  
  The slit orientation was chosen in a way to put a second star in the slit (see FC).
  Please center the slit in between the two objects.
  
  1 OB: CAHA2 (50 min 47 s )
  
  
  
  3) CAHA3:
  -------------------
  RA (J2000): 04 40 39.33
  DEC (2000): 25 23 01.99
  J-band: 17.4 magnitudes
  
  Acquisition Reference star: yes!
  Reference star:
  RA (J2000):  04 40 39.70
  DEC (J2000): 25 23 04.34
  
  Slit orientation: 64.26 degrees from north to east
  
  The slit orientation was chosen in a way to put also the acquisition reference star
   in the slit (see FC).
  Please center the slit on the science target.
  
  
  3 OBs: CAHA3-A, CAHA3-B (59 min 47 s each), CAHA3-C (41 min 46 s)
  The first 2 OBs are identical! The constraints on the OB length required to split
   the total time in two OBs.
  The third OB is required to achieve the forseen S/N

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• clear; seeing <~ 0.8 arcsec

Time-Critical Aspects

• The OBs have to be executed at the beginning of the night as the objects
   are setting quickly.
  For the first ~2.5 hours of the night (before 15th of Feb.) the objects have airmass
   ~< 2.5.
