TOOLBOX cont2 (MPIfR)
---------------------

CONT2 is a subpackage of the Toolbox package for the analysis of single-dish
radio observations (e.g. Effelsberg, Medicina).

(Very) brief user guide:
-----------------------

Your raw data should be stored in Toolbox formatted files and ideally but
not necessarily reside in your local working directory.
To start the program just type:

cont2

Then appears the prompt, and you can type all the cont2 commands. For instance:

Cont2> changefiles=/Locale/data/E01 

will load the E01 raw data file where your data should be stored
(or the one that corresponds to your observations, this is only an example)

A very interesting command is:

Cont2> help

which gives some information about all available commands. 

It is also possible to make macros that can be written in a text file and
then loaded in cont2. As an example, suppose you have a file macro: 'b6.com'
to make the analysis and reduction of the 6cm observations. Yo can load these
commands just typing:

Cont2> co=b6.com

and then:

Cont2> read

------------------------

EXAMPLE OF USE:

NOTE: User input is after 'Cont2>' prompt. The remaining text is output from
the program.

------------------

The first command selects the appropriate E-file. The program says the
number of scans stored in this file and also the first and last one.

With the second and third commands you select a macro to do the reduction
(b28.com) and the program reads it. Then you see the list of commands in
that macro.

The next step is to select one scan number contained in that e-file (e.g 3560).

And when you type 'end' cont2 runs the macro and gives you the desired output.

Finally 'finis' closes the session.
