Notes. Column 2: if there are six wavelength values (26–29, 34–37, and 44–46), they refer to the passbands of the left pseudo-continuum, feature, and right pseudo-continuum. For those 4000-Å break indices (the 30–33), the four values are for the passbands of the left and right continua in turn. For the indices 38–43, they are CaII or Paschen (PaT) indices and they have five passbands for the pseudo-continuum (the first 10 values). For Ca1, Ca2, and Ca3, there is a absorption feature passband (the last two values). For CaT (=Ca1+Ca2+Ca3) and PaT, there are three absorption feature passbands (the last 6 values, for CaT, they are the combination of the last two values of the indices 39–41). For CaT* (=CaT−0.93PaT), there are six absorption feature passbands.
