SCUSETENV - Set the startup environment variables for SURF

Description:

This script sets the standard DATADIR and SCUBA_PREFIX environment variables given a UT date.

Usage:

scusetenv [UTdate]

Examples:

scusetenv

Set DATADIR and SCUBA_PREFIX for the current UT date

scusetenv 19980201

Set DATADIR and SCUBA_PREFIX for the data observed on date 19980201

Notes:

• Currently this routine only works for the JAC and JCMT systems. This is because the data are stored in standard directories and indexed by YYYYMMDD UT date.

• ORAC_DATA_IN environment variable is also set (only relevant for users of the ORAC-DR pipeline)

• If this routine is run from a non-JAC/JCMT site DATADIR will not be set but SCUBA_PREFIX will be set.

Parameters

UTdate = YYYYMMDD format string (Optional) The UT date of the data to be processed (in YYYYMMDD format). The default value is to use the current UT date

Implementation Status:

This script should be sourced (not executed) since the environment variables should be set after the script has been read.
