... Many Miriad tasks support on-the-fly selection and averaging of the channels to be processed. ... Channel-0' data (data formed by averaging all spectral channels together) are also treated as continuum data. ... For the spectral data, if the channel number does not correspond reasonably directly with velocity ( e.g. if Doppler tracking was not used), then it might be desirable to resample the spectral data at equal increments in velocity. ... channel . This gives raw or averaged spectral channels. ...

Table: CCD keywords for overscan fitting . ... In case of a zero order fit the correction is a simple constant. ... After an interactive fit has been completed the command will ask you if you want to fit the next frame interactively as well, or if you want to apply the overscan correction to all subsequent frames. ...

... These steps must be run on the qpoe file before the dewobble scripts are implemented. ... This is because the phase of the wobble is fixed to the space craft clock. c) Create an ASCII file with the listed obi start and end times. ... The IRAF script 'phase_repos' breaks up each obi of the qpoe file into a number of phase bins. Then a source centroid is calculated for each binned qpoe file. ... Each binned qpoe file is labelled by two indices, the obi and the phase number. ... Run phase_repos: . ...

We have analyzed the UV continuum light curves of 2535 pixels obtained during fifteen separate observations of active regions with the Ultraviolet Spectrometer and Polarimeter (UVSP) on board the solar maximum mission in 1989. ... The distribution N(v), which describes the number of pixels having maximum power at frequency v, is strongly concentrated in the 2 - 5 mHz band with a distinct maximum at 3 - 3.5 mHz. ... No clear correlation is found between the maximum power and the count rate in a pixel. ...

This document describes when and how to use name-based virtual hosts. ... IP-based virtual hosts use the IP address of the connection to determine the correct virtual host to serve. ... To use name-based virtual hosting, you must designate the IP address (and possibly port) on the server that will be accepting requests for the hosts. ... For example, suppose that you are serving the domain www.domain.tld and you wish to add the virtual host www.otherdomain.tld , which points at the same IP address. ...

. This diagram shows how the precedence rules may be used to achieve the effect of rows being separated by a border. There is no border above or below the table and there are no vertical borders at all. The table shows a table of three columns and three rows. Each cell contains an integer that labels it. The top row is separated from the second by a solid black border. The second row is separated from the third by a solid black border as well. Return to image.
