DSSI OT Details

This page explains how to configure the Gemini "Visitor Instrument" component for use with DSSI.
Name
The Visitor Instrument name should be set to "DSSI".
Exposure Time
The "Exp Time" field should be filled in with the total desired integration time for each target.
Position Angle
The "Pos Angle" field sets the position angle of the instrument on the sky (degrees East of North). It is not expected that this field will be used with DSSI.
Wavelength
The "Wavelength" field is used by the TCS to calculate the relative atmospheric dispersion with respect to the guide wavelength, and should be set to 0.7 microns for all DSSI observations.
