Notes.

^(a)

The values have been aperture-corrected and adjusted for Galactic extinction. We have also calibrated for possible instrumental offsets, using standard stars in the UVOT FOV.

^(b)

The relevant UVOT-filter central wavelengths are 3465, 2600, 2246, and 1928 Å for U, W1, M2, and W2, respectively.
