Decorative shadow for 50% width subcontainers

Catalog entries:

  • 2MASS J19240775+4902249
  • KIC 11295426
  • GSC 03551-00189
  • TYC 3551-189-1
Notes from the researcher:

Same data as run 182, but using the alternate weighting scheme that treats the surface correction as a systematic error -- biasing the fit to low frequencies. This is expected to reduce the optimal mass while still providing a satisfactory fit to the echelle diagram.
