... 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. ...
