Next: Sky Subtraction Up: Construction of Flat Previous: Standard construction . For a number of projects where very deep integrations and accurate flat fields are required, and the targets are point sources or much smaller than the frame size, the sky background itself can be used to calculate the flat field. ... Use STATISTICS/IMAGE to calculate the image median, and COMPUTE/IMAGE to divide by this to get the normalised flat field. ...

... This calibration approach is recommended when dealing with high frequency data from the old ATCA correlator, especially at 3mm wavelengths. ... The approach described here exploits the dual frequency bands that were available with the old correlator. ... Rather the current approach assumes that you have a single Miriad dataset containing bandpass calibrator, phase calibrator, flux density calibrator and program source. ... MFCAL . ...

... We have been upgrading the software front-end to WASP (Wideband Autocorrelating SPectrometer, operating from 800 to 4000 MHz) from Lynx-OS to Real-Time Linux and will discuss Real-Time software aspects. We are using a standard parallel ``PIO'' card to receive data from the spectrometer and standard GPIB interfaces that drive a frequency synthesizer for bandpass calibration. WASP and its front-end computer are fully mobile and can be taken to any suitable radio telescope. ...

SAOtng supports display of photon event data contained in raw files, similar to its support for FITS Binary Table extensions (e.g., X-ray event lists). ... Because event files do not usually contain enough information to generate an image, we have adopted some conventions for specifying how to interpret the data in these files and for how to bin rows of events into images. To image an event file, it is first of all necessary to define the structure of the events in the event file. ...

... Alternatively, the PI channel boundaries will be read directly from the data subspace extension of the input image (not yet implemented). ... EPIC PN offset columns (as specified in the offsets extension of the photon event list) are set to zero in the exposure map, if they had been removed from the input reference EPIC image. ... The task tries to determine the exposure time by looking for gti extensions in the input image of the form STDGTInn, STDGTIn, STDGT, or GTI. ...
