L-Narrow Cal Values

L-Narrow Cal Values


On 18 December, 2000, the L-Narrow cals were re-measured, with the results shown below. Prior to 18 December, '00, the L-narrow Cal values were assumed to be 1.85 & 1.91 for A & B polarizations, respectively, at all frequencies. This means that gain curves obtained before 18 Dec '00 assume old cal values, and curves determined after 18 Dec '00 assume new cal values.
BE SURE YOU KNOW WHICH CALS TO USE!
