VIRGO MNEMONIC INFORMATION TABLE

The following table lists the VIRGO mnemonics with specific FOT actions to take in response to limit violations. The general rule for mnemonics not listed here is that RED limit violations require immediate notification to the OE and the experiment representative. YELLOW limit violations require notification to the OE and the experiment representative only when they are present (or as soon as they arrive).

An anomaly report is required for any limit violation unless the table below or an Expected Limit Violation sheet specifically directs it is to be ignored.
