ECHOMOP may be used in a variety of ways depending upon the expertise of the user.
The most convenient method for normal use is to start the main ECHOMOP task itself. This task provides a guided path through the processes in a standard reduction.
ECHOMOP is a menu driven program which drives all the other programs in the package. ECHOMOP 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 recommeded next step , it is only necessary to hit /return/.
The package uses a disc based 'reduction file' to pass objects between its various component tasks. The user will initially be asked to provide a filename 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 many users will wish to delete them as soon as the reduced spectrum has been obtained.
To start a reduction type
