Next: Reading and Writing Visibilities Up: UV Data Sets Previous: General . The routine uvopen opens a uv data set and readies it for access. Here dataname is a string giving the data set's name. Status can be either 'old' or 'new' , depending whether an old data set is being read, or a new data set is being created. Tno is an integer handle passed back by the open routine (and is used for all future access to the data set). The routine uvclose closes the data set. ...

... The system is based on two straight lines ("axes"), perpendicular to each other, each of them marked with the distances from the point where they meet ("origin")--distances to the right of the origin and above it, the origin being taken as positive and on the other sides as negative (see drawing below). ... One system (" polar coordinates ") uses the length r of the line OP from the origin to P (i. e. the distance of P distance to the origin) and the angle that line makes with the x-axis. ...

This is a color composite image made by Karen Gloria at Hopkins Observatory using a 6-inch refractor and a 512x512 element CCD detector. ... This is a planetary nebula (see also the Planetary Nebula page on this server). It is relatively small, measuring approximately 8x4 arcminutes. Overall, the surface brightness of the extended ionized gas emission is one of the highest for any PN and therefore this object is easily seen through even small telescopes (including most finders). ...
