Installing NCDRT

NCDRT uses IDL 5.4 or higher. Untar the NCDRT_V2.1.tar file to a directory of your choice, for example in /home/your_name/idlproc/NCDRT/. Also include the following line in your .cshrc file:

setenv IDL_PATH /home/your_name/idlproc/NCDRT:${IDL_PATH}

This will make IDL search this directory for programme files.

Some routines in NCDRT use the /bin/rm and /bin/cp command to remove and copy temporary files. On some computer systems these commands are located in the /sbin or other directories. Please check the location of these executables before you run NCDRT. If necessary make changes in the following routines:

delete_from_cal_table.pro

read_list.pro

write_2_cal_table.pro

look for the USER: RM and CP commands keyword in these files.

The routine read_list.pro uses the command /bin/ls. Look for the ‘USER: LS command’ keyword in this file if a change is required.
