  Low-resolution spectroscopy in the Z, J, H, K bands of a faint white
dwarf, to be done under little restrictive constraints. 

  When identifying the field, please keep in mind that the position
angle of the slit is E-W (orientation not indicated in the finding
chart). 

  Some OBs longer than 1 hour. Admitted to keep the program efficient,
taking into account its high priority and the relaxed constraints.

  Special calibration needed: for each wavelength setup, one calibration
OB (provided by the user) at the beginning and another one at the end must 
be executed. Names are self-explanatory as to which calibration is
linked to which OB. If the OBs in K or Z are executed contiguously, only
one calibration with B and one with G is needed.

  No time-critical aspects.

  ! NOTE: the user defined by mistake a central wavelength of 1.65
    microns in some of the OBs intended for K-band spectroscopy. The mistake
    was detected by PSO only after execution of the first K-band OB
    (which turned out to be actually H-band). In agreement with the user, 
    the following actions have been taken:

    1- OB 111255 (OBh) has been shortened so that after execution of this OB,
       plus the already executed H-band time, the time spent in the H
       band is as close as possible to what was originally intended.

    2- The central wavelength of the remaining OB to be executed in the
       K band, 111775, has been set to the correct value, 2.20 microns.

    3- A new OB, 114623, has been created to account for the time
       originally intended for the K band, part of which was actually
       spent in the H-band. 

    PLEASE NOTE that, in agreement with the user, OB 111255 will be
    calibrated with the normal calibration plan. The calibration OBs 
    submitted by the user for the H band, that were already executed,
    should not be reexecuted. Likewise, 

    - 111748 (OBk2) should be calibrated with 111750 (OBstBk1) and 111753 
      (OBstGk1)
    - 114623 (OBk3) should be calibrated with 111774 (OBstBk2) and 111775
      (OBstGk2)

    With these changes, the total execution time of this program remains
    at the time allocated by the OPC.
