Finding Charts

 

By default the observer will use the optical Digital Sky Survery or the 2MASS image of the field in the Position Editor to identify the target during acquisition. An additional finding chart should be provided any time there are uncertainties about the identity of the target, e.g. crowded fields or very faint sources.

Starting with OT Abeja (2006B) finding charts should be submitted to Gemini using the File Attachment tab of the Gemini Science Program component in the Program Editor.

Finding charts should follow these guidelines:
The following is an example of a good finding chart.  The bandpass and source of the image is given and the orientation, scale, target, and offset star are clearly marked.

The following is a poor finding chart.  The target is indicated but the orientation, scale, bandpass and instrument field-of-view are not given.
