... The Miriad task uvgen can be used to simulate a variety of observing modes. ... Simulating a telescope approximately, let alone in some detail, requires a good many parameters. uvgen takes an appreciable number of parameters and input files to describe the telescope, correlator and source. Fortunately keyword and set-up files for some common situations exist ( e.g. simulating the ATCA and VLA). ... For example, to load typical parameters for the ATCA, use miriad% source $MIRCAT/uvgen.def.atca . ...

. Next: EPN_REDIST Up: EMOS_REDIST Previous: Generation from Ground Calibration Contents . Many calibration observations of celestial targets have been used to measure the response function of the MOS detectors as a function of observing date. The response has evolved, particularly at low-energies, and is currently modelled by an empirical formula designed to give consistent results between the EPIC-pn, EPIC-MOS and RGS cameras.

... To help you get the necessary calibration data in the least observing time, the planning program generates a schedule of required observations. A considerable amount of photometric expertise is built into this program, so that observers without much photometric experience can confidently adopt its recommended defaults, and obtain a plan that should be satisfactory for most photometric observing programs. ...
