ECH_BLOCK

BLOCKDATA to initialise spectrograph configuration

Description

This refers to the ECH_PARAMS COMMON block, which contains the parameters of all possible spectrographs, not to the ECH_COMMONCOMMON block, which contains the details only of the current configuration.

This BLOCKDATA initialises the COMMON block in such a way that a call to ECH_INIT without a call to ECH_LOAD to load the parameters of a specific spectrograph configuration will use the values which are correct for UCLES. These values also serve to provide defaults for quantities which are not overridden as a result of ECH_LOAD.

Bugs

None known.
