Table 6
Parameters for fits of ellipsoidal brightness distribution.
| kc | Spectral index of circumstellar component |
| fc | Fractional flux of circumstellar component |
| fh | Fractional flux of halo component |
| fLor | Weighting for radial profile |
| la | (log) Half flux semimajor axis |
| cosi | Axis ratio of isophotes |
| θ | Position angle of major axis, east from north |
Notes. la is shorthand for log 10(a/ 1 mas). In practice, the redundant parameter fs, fractional flux of the star, is also included, together with a constraint fs + fc + fh = 1.
