ECH_BLOCK
BLOCK
DATA
to initialise spectrograph configuration
This refers to the ECH_PARAMS
COMMON
block, which contains the parameters of all possible
spectrographs, not to the ECH_COMMON
COMMON
block, which contains the details only of the current
configuration.
This BLOCK
DATA
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
.
