Claim One:
1. A method comprising: receiving values of one or more measured variables from sensors of a Master Oscillator Power Amplifier (MOPA) system, the received values indicative of a fluorine concentration in chambers of the MOPA system, the received values affected by one or more specified variables; resetting, based on a change in target bandwidth, a portion of covariance values within a covariance matrix, the portion of covariance values indicative of a first specified variable of the one or more specified variables; estimating, using a computing device, an effect of the one or more specified variables on the received values, the estimating performed using a recursive least squares (RLS) algorithm and the covariance matrix having the reset portion of covariance values, the RLS algorithm including a quadratic term of the first specified variable of the one or more specified variables that has a quadratic relationship with one of the one or more measured variables; and directing an injection of fluorine into the chambers of the MOPA system based on the estimated effect and the received values.
