ECHOMOP may be used in a variety of ways depending upon your expertise.
The most convenient method for the first-time user is to start ECHOMOP with a menu interface (command echmenu). This provides a guided path through the processes in a standard reduction.
echmenu is the monolith program which drives all the other programs in the package. echmenu will always provide a default for the next task to be performed, and this will usually be the correct one for a 'standard' reduction. To accept the recommended next step, it is only necessary to hit Y/return/.
The package uses a disk-based 'reduction file' to pass objects between its various component tasks. You will be asked to provide a name for this file, which will be created in the current directory. This file is permanently associated with a particular set of data frames (object, arc, flat etc.) thereby providing the ability to replay any aspect of the reduction at a later date. Reduction files can occupy a large amount of disk space however, and you may wish to delete them as soon as the reduced spectrum has been obtained.
To start ECHOMOP using a guided menu type:
% echmenu/return/
at the command-line prompt.
To run any particular ECHOMOP command just type its name at the command line prompt.
For example:
% ech_locate/return/
would run the order location task ech_locate.
