Some Useful Routines for On-Line Data Analysis

 

In this section we describe some useful routines for quick-look on-line analysis of your data. For a complete description of the routines, and for a description of analyzing HI spectra, look at the Spectral Line Appendices. If you want to delve into the mysteries of Analyz, you can obtain a copy of the Analyz manual either through your Friend at the Telescope, or through an anonymous ftp on ftp2.naic.edu (cd pub/Analyz/Analyzguide).

Real Time Data Display:

You can now use IDL to display your data as it comes from the telescope. This is done via the following commands (note that IDL is not case-sensitive):

% gousr
% cd a9999 [or whatever your project number is
% idl
IDL> @corinit
IDL> openr,lun,'/share/olcor/corfile',/get_lun
IDL> cormon,lun

To stop the online display, just hit control-C in the IDL window. If you wish to change the horizontal or vertical axis, just type ver,low,high or hor,low,high . Other IDL commands can be found online at http://www.naic.edu/phil/cordoc.html

Setting Up Analyz:

Attaching Data:
(NOTE: Only one data file can be attached at a time. If you wish to compare two data sets,
save the results you wish to compare into a register(s) and then attach the new data file.
