Hi All.
Please what is the threshold for sun glint masking in SeaDAS (in the default exclusion flag). Not sure if it's SWIR(0.005)?
Thanks.

The HIGLINT flag is set when the Cox-Munk glint coefficient (l2gen product glint_coeff, normalized glint radiance for solar irradiance of unity) is >= 0.005.  The glint_coeff has no spectral (wavelength) dependence.

Thanks Bryan!

Are those pixels masked out by default, or I need to use the flag to mask such pixels from the entire scene?

The flag is not masked by default, so you would need to apply it yourself.
