\caption{\label{tab:2004}Log of observations from 2004--2006. All fluxes are presented
  in mJy. Spitzer fluxes are from the third delivery of data from the
  "c2d'' legacy project, except the $70~\mu$m data of all sources and
  the $3.6$, $4.5$, $5.8$, $8$ and $24~\mu$m data of OO~Ser, which
  were extracted by us from MIPS and IRAC images improved and
  published by the "c2d'' legacy team. All Spitzer fluxes are colour
  corrected.}
