 {$^a$ Line fluxes (in erg cm$^{-2}$ s$^{-1}$) 
  measured in Chandra/LETG AY Cet summed spectra, and corrected by the
  ISM absorption. 
  log $T_{{\rm max}}$ indicates the maximum
  temperature (K) of formation of the line (unweighted by the
  EMD). ``Ratio'' is the log~($F_{{\rm obs}}$/$F_{{\rm pred}}$) 
  of the line. 
  Blends amounting to more than 5\% of the total flux for each line are
  indicated. For some lines not identified in APED, a tentative identification as 3${\rm rd}$ order emission of intense lines is suggested in the ``Blends'' column.}
