Spreadsheet from Dan VanWinkle on how to keep 16 MV when we lose one RF
station. (May 2007). All values are in kVKV.

EPICS CONFIG LOAD:
SCP config files for use in the parking of a given HER RF station exist. The configuration region is called HER_GAPV (SCP path INDEX -> CONFIG -> MISC CONFIG -> EPICS CONFIG -> HER GAP VOLT) and the NORMAL directory has setups for parking each station. Configs for 2007 are still in the works These new configuration files save the following parameters for each RF station in HER:
- Desired gap voltage
- LFB woofer link state (ON/OFF); meaning woofer is turned on or off. This does not load LFB configurations, it just tell tells the given RF station to woof or not.
