Next: DISH : The Single Dish Environment in AIPS++ . ... We present the SDImager tool which is designed to be the single dish imaging component of DISH in AIPS++. ... Recent work has concentrated on developing an imaging tool for single dish on-the-fly (OTF) observations using the same imaging class library as used for synthesis imaging in AIPS++. ... The initial single dish imaging tool in AIPS++ provides a few tools to examine and image these types of observations. ...

... HST . How are observations affected when only a single guidestar is acquired? ... Data . ... HST Overview . ... Retrieving HST Data . ... Target Acquisition . ... In this situation, the roll of the telescope is under GYRO control, which may allow a slow drift of the target on a circular arc centered on the single guidestar. ... To calculate the approximate magnitude of the drift of the target on the detector, you will need to find the distance of the target from the acquired guidestar. ...

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...
