... For a good discussion of the theory and practice of combining single dish and mosaic data, see the paper by Snezana Stanimirovic (ASP Conf. ... Just as there are two approaches to mosaicing (the joint and individual approach), Miriad provides two approaches to single-dish combination - the linear and a non-linear methods, using tasks immerge and mosmem respectively. ... Given that combining mosaic and single-dish data can be a bit of an art, its worth doing a few checks of the result: . ...

This document discusses the conventions for combining region and table filters, especially with regards to the comma operator. Filter specifications consist of a series of boolean expressions, separated by commas. ... Region and table filters can be combined: foo.fits[circle(10,10,3),pi=1:5] or even: foo.fits[pha==1 (10,10,3),pi==2 (20,20,8,5)] In these cases, it is not obvious whether the command should utilize an or or and operator. ...

. You can also use the find command to find a file and then carry out a command on that file. To do this use the command: find pathname -name filename -print -exec command {}\; . To be prompted for confirmation before the command is executed use the command: find pathname -name filename -print -ok command {}\; . The command must be followed by a \ (backslash) and a ; (semi-colon). The {} (pair of braces) substitute the pathname of the file that is found as an argument to the command. Examples .

... The Si VIII line width measurements and N e estimates based on SUMER observations are combined with LASCO and UVCS output to provide an overview of its variations with height above a polar coronal hole. ... Combining the Si VIII half width at 1/e of the peak intensity with the UVCS O VI half width, we find a small increase of the half width from 1 to 1.2 , then a plateau until 1.5 , thereafter a sharp increase until 2 , finally a more gradual increase reaching 550 km s -1 at 3.5 . ...

Prague, August 16, 2006 . Our trial revision of the GCVS data for several southern constellations show that type changes are not needed for most stars. ... We suggest to add one more symbol combining types, in the cases when two or more classification options remain for the same star, for example, EC|Ell, EC|RR (here EC means a contact eclipsing binary, this is one of our suggestions from next slides). ... Moreover, it will simplify moving stars from the suspected-variable catalogue to the GCVS. ...
