841. CCD Charge Shuffling Improvements for ICE
... At the Kitt Peak National Observatory, this has included data acquisition using the ICE ( IRAF Control Environment ) package that was developed in coordination with Skip Schaller at Steward Observatory. ... Improvements to ICE are described that support a dual exposure mode implemented via charge shuffling techniques. Charge shuffling involves repeatedly shifting the charge back-and-forth from side-to-side of a CCD while nodding the telescope alternately from an object to a blank sky position. ...

842. Automated Photometric Calibration Software For IRAF
... New IRAF tools for the photometric calibration of optical/IR images are presented. The new tools are standard star catalog and world coordinate driven, requiring both accurate standard star catalog coordinate and accurate image coordinate data. Network access to standard star catalog servers is supported. ... The photometric calibration software will automatically convert the standard star coordinates from the standard star coordinate system to the image coordinate system. ...
