This plot

This plot shows the relation between SNR (called 'snr' in the database) and ETC flux ('flux_tot') for the HARPS IDPs. The flux_tot parameter measures the flux of the object during the exposure. The snr parameter measures the photon noise of the target flux, convolved with the quality of the reduction process. In theory a square-root law is expected if no additional noise sources (introduced by reduction artefacts) exist. See the plot tutorial for more.

HAM stands for high-accuracy mode, EGGS for the high-efficiency mode.

The upper and lower boundaries are scaled square-root laws and purely empirical. They are plotted for orientation and are not fits.

NOTE: The 'Data downloads' for the HAM mode may take very long or time out.  


General information

Click on any of the plots to see a close-up version.

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • statistical averages are indicated by a solid line, and thresholds by broken lines
  • outliers are marked by a red asterisk. They are defined as data points outside the threshold lines
  • "aliens" (= data points outside the plot Y limits) are marked by a red arrow ( or )
  • you can download the data for each parameter set if the 'Data downloads' link shows up
