Spectral Extraction at SPE level
The ``standard'' spectral extraction procedure is carried out at the
SPE level of the jemx_science_analysis script by
re-formatting the source fluxes found at the IMA step. The file jmx2_srcl_res.fits serves as input for the spectral extraction in
each ScW. It is important to note, however, that j_ima_iros
will always find a little bit different source positions in different
ScWs. The deviation of the found source position from the true one may
lead to an error in determination of the source spectrum. To avoid
this difficulty it is recommended to create a ``user catalog'' with
the names and positions of the sources for which you want to extract
the spectra.
