General Description

This is an ISAAC near-IR spectroscopic followup to a WFCAM narrowband
 survey for H-alpha emitters at z=2.23 in the COSMOS field. These observations consist
 of faint (K=18-19) targets selected with narrowband excess flux at 2.121um, and
 we aim to identify emission lines to confirm the narrowband selection.

Due to the faint nature of the targets, in all cases we target a nearby bright acquistion
 object and then set PA and offset to target, keeping the reference on the slit to
 help with identification of the science target in the 2D spectrum. This has been
 a strategy that has been useful in the past. The reference objects have been chosen
 to be near and as stellar like as possible. They generally have K=15-16 (Vega).

All target coordinates refer to the reference object, and the offset is to the science
 target in the sense that east and north are positive. The PA should be set such
 that the reference and target remain on the slit.
