General Description

This is a simple spectroscopy programme with one slit setting of the 1"
 slit on the brightest cluster source J1836.3CRa using both the SH and SK filters.
 

The brightest source in the field-of-view (FOV) is the star at about 21" to the
 north of J1836.3CRa with m_H=8.93 and m_K=8.79. This star is not contained in the
 slit, but in the FOV during acquisition.
Therefore, acquisition is done with a narrow-band filter to prevent saturation.
 
DIT and NDIT in the acquisition template are based on our experience from previous
 narrow-band imaging of the FOV. They should be appropriate to clearly reveal J1836.3CRa
 for direct slit centering. If there are problems with a direct acquisition on J1836.3CRa,
 please make the acquisition on the northern star as a reference object (as labeled
 in the finding chart). In this case, please use the reference object coordinates
 RA=13:45:01.357, DEC=-00:20:31.01 and "Alpha offset from Ref. Star (arcsec)" = 7.0,
 "Delta offset from Ref. Star (arcsec)" = -20.3.

Special Execution Requirements

As indicated by the User Priority, the completion of the SK spectroscopy
 has highest priority.

Special Calibration Information

Given that telluric standards, flats, and arcs are included in the calibration
 plan for the gratings used in this programme, we do not see the need for calibration
 OBs. However, we would prefer an A0 or G-type star as telluric standard.
