Notes
-----

* Quantities marked with an asterisk are nominally read from the 
NCLA and NCLB banks.  If desired, they can be read from this bank 
instead by using the "$custom_ncd_electronics $on" command in your 
command file, and setting the desired parameters to something 
other than -9999.  If the values are still -9999., they will be 
read from the NCLA/B bank.
