Flux Calibration


This release of ECHOMOP provides no special support for flux calibration of the extracted spectra. FIGARO provides extensive support for this procedure, including many standard star data tables.

It should be noted that due to the extremely high resolution of the spectra produced by UCLES, there are unlikely to be sufficiently high resolution data available for the flux standards.

A common situation is that the FIGARO table for the standard contains (at most) one sample (flux) point per order, and that such points are often 40 Angstrom averages. In such cases it is difficult to ascribe much confidence to the resulting fluxes.

A program of high-resolution observations (of commonly used flux standards) to combat this problem is being planned.

Output ECHOMOP data files (generated using ech_result) may be read into the appropriate FIGARO tasks.
