Manual Reduction


Manual reduction using ECHOMOP is available at two levels:

A menu driven, guided reduction.

    - ECHMENU     provides menu of all tasks

A completely manual selection of processing steps one after another when required. The set of tasks available to the user at this level consists of the following ECHOMOP specifics:

    - ECH_DECOS1  detects and flags cosmic ray pixels

- ECH_DECOS2 detects and flags cosmic ray pixels

- ECH_LOCATE locates orders in a frame

- ECH_SLOPE measure average order slope

- ECH_TRACE traces orders already located

- ECH_TRCSIS does trace consistency checking

- ECH_TRPLT plots order traces graphically

- ECH_SPATIAL calculates the profiles (spatial)

- ECH_LINLOC locates arc lines

- ECH_IDWAVE identifies and wavelength calibrates

- ECH_WVCSIS does wavelength scale consistency checking

- ECH_EXTRCT extracts orders

- ECH_2DFIT distortion fitting for an order

- ECH_2DEXT extracts distorted orders

- ECH_MDLBCK models global scattered light background

- ECH_FFIELD calculates flat field balance model

- ECH_PROFILE calculates object profiles

- ECH_SKY calculates sky background

- ECH_SCRUNCH scrunches extracted orders

- ECH_TUNER interactively sets tuning parameters

- ECH_PLOT plots/prints all stages of reduction

- ECH_RESULT handles flexible output of resulting reduced spectra etc. to .sdf, ASCII format files.

- ECH_ONE set single order operations (ICL usage only)

- ECH_ALL set all order operations (ICL usage only)

- ECH_FTRDB generate a database file using a .ARC line list

These commands may generally be used from an ICL command prompt or from the system shell prompt.
