Next: Pulsar bin-mode observations Up: ATCA Bin Mode Observations Previous: ATCA Correlator Bin Modes . Miriad 's atlod task has an option, options=hires which converts a RPFITS file observed in high time resolution bin-mode into an apparently normal dataset with fine time resolution. ... In high resolution time mode, the time difference between consecutive integrations might be smaller than this tolerance. ... Miriad manager . ...

... There are number of features that can be set by the user in the Sparkle Dialog box. ... The Sparkle plug-in computes the luminosity (level of whiteness) of each pixel in the image (the user can see this when the progress window labeled Generating luminosity array... is displayed). ... The threshold value is currently a slider/text field pair which have a precision of .0001. ... Like the Threshold value, the Flare Intensity has both a slider and a text input field for specifying its value. ...

Allows you to specify a desired wrap for the azimuth axis and the instrument rotator. ... If the axis is being driven in mount coordinates then your wrap preference will be recorded, but ignored (for mount coordinates you specify exactly the position you want; a different wrap is never chosen). The wrap preferences are: . Nearest pick the position nearest the current position . ... Positive pick the larger angle . Middle pick the position nearest the center of the allowed range of motion . ...

Next: Quadrant DC Offset Removal in NICMOS Images Using an Eye-pleasing Criterion . ... This paper describes a simple imaging model which allows the limits of dithered imaging to be readily appreciated and briefly reviews available software. ... Dithered imaging can improve this sampling. ... ACOADD was originally developed for combining images with different PSFs but can also be used, with shifted PSFs and sub-sampled output images, for combining dithered under-sampled images. ...

... Meta Index / Home Page / Description By default, an ARF will be created which has been corrected for the area lost by the gaps between CCDs and by bad pixels. ... The extendedsource option tells arfgen to produce the ARF relevant for an extended source. ... In practice, for an extended source the ARF has no correction for encircled energy, the mirror vignetting is averaged over the whole source area and area lost due to bad pixels and chip gaps is not convolved with the Point Spread Function (PSF). ...

. To make a lasting change, create a file named .exrc , containing the set commands, in your home directory. The next time you use vi these options will take effect and will remain in force until you edit the .exrc file to change them. You can, of course, temporarily change the value of any option. List of options . Examples . Did You Know? .

The new algorithm considers only data from segment A of the FUV detector and requires a signal-to-noise ratio of 25 to compute an accurate centroid. ...
