Master flats and arcs with binning 2 for RILD are
available for all the grisms
and in /data/NTTOPS/pipeline_database/EMMI/master_arcs.
Adequate calibrations will be automatically copied
from there in the directory where you are working
(usually /data/raw/YYYY-MM_DD on the NTT offline
machine) once you launch the script
For BLMD and REMD spectroscopy or RILD in binning 1 you will have to built you own master flat in the afternoon, using the script emmi_fcomb.prg, also available on the offline machine.
A wavelength calibration will also be necessary for REMD, BLMD and RILD in binning 1 mode; this one can be obtained with the MIDAS context long
The extraction of the spectra can be done in two ways:
The script concept is based on the
usual MIDAS scripting convention, which means
issuing the command, followed by some parameters.
On the offline workstation go to the /data/raw/YYYY-MM-DD directory, type inmidas, then, from a MIDAS prompt, type:
@@ emmi_quickred inputframe outputframe mode [masterflat] [masterarc] [extragalactic?] [snr]
inputframe = name of the input frame (with fits extension)
outputframe = name of the output frame (no bdf extension)
mode = which EMMI mode you are using. Can be BLUE or RED
[masterflat] = name of the masterflat frame (no extension). There is no need for it if you are working in RILD, bin=2 (place a ? instead)
[masterarc] = name of the master wavelength calibration (no extension). Again no need for it if you are working in RILD, bin=2 (place a ? instead)
[extragalactic] = 1 for interactive extraction, 0 for automatic extraction. Defaulted to 0
[snr] = 1 for estimate of S/N ratio of the spectra, 0 for no estimate. Defaulted to 0
