There are two available methods (parameter REDUCTION): STANDARD consists of the following steps \\ . Background correction \\ . Flat field correction (optional, depending on FFOPT) \\ . Order extraction \\ . Calibration in wavelengths \\ . Response correction (optional, depending on RESPOPT) \\ . Order merging \\ The parameters involved in this command are displayed by SHOW/ECHELLE. Before using the command, the following sections must be checked: 2. Background 4. Extraction 7. Rebin 8. Flat field correction 9. Response correction 10. Merging \up\sy Syntax: REDUCE/ECHELLE input output [bkcor] \ys\pa input = raw image \ap\pa output = 1D reduced spectrum \ap\pa bkcor = if an image name is provided, a simplified reduction is performed, including background correction, extraction, rebin, and theoptional flat-field correction. \ap\no Note: \on\exs Examples: \ex REDUCE/ECHELLE raw spectrum \xe\sxe
