How are gains mentioned in SeaHawk L2 metadata calculated?

Hello,

I downloaded SeaHawk data and found the following gains in metadata.
[1.23070000000000 1.21280000000000 1.14780000000000 1.18620000000000 1.20230000000000 1.18570000000000 1 1]
Were they derived by based on "Sensor-independent approach to the vicarious calibration of satellite ocean color radiometry" method?

If so, was MOBY data used for comparing SeaHawk data or climatology?
I found only a couple of days when SeaHawk had matchup data with MOBY.

Thank you.

Yes, the Franz et al., 2007 approach was used, but with limited coverage over MOBY, the ocean reflectance model of Werdell et al., 2007 was necessary. Several clear ocean scenes were used.
