\caption {Fluxes, molecule production rate\&production rate
  ratios and dust continuum reddening of 9P/Tempel 1 during 2--10~July 2005. 
  The fluxes F and  reddening slopes~$R$ are measured in circular apertures of 
  fixed radii centered at the brightness peak in the coma. $Q_{\rm mean}$ and 
  $R_{\rm mean}$ are mean values of the production 
  rates and reddening slopes, respectively, obtained from the flux and 
  slope measurements with radii
  5000, 10~000, 15~000, and 20~000~km. The continuum filter image used for 
  dust continuum subtraction in the gas filter images is indicated in table 
  column DCONT; if two filters are given, the flux and production rate numbers 
  are the mean values obtained from measurements using either of the two filter images as
  reference for the dust continuum subtraction. The table lists logarithmized
  values for fluxes and production rates. "NM'' means "no useful measurement 
  obtained''. Flux~$F$ is measured in erg/s/cm$^2$/\AA, production
  rates~$Q$ in molecules/s, reddening slope~$R$ in \%/100~nm, aperture radii are in km
  at the distance of the comet. All results are based on narrowband filter 
  imaging of the comet obtained with the EMMI instrument at the ESO NTT
  telescope in La Silla. Measurements, obtained at very high airmass where the flux
calibration may be badly affected by extinction, are indicated by symbol *.\label{production_rates}}
