FWAVECALIB.cl, FWAVECALIB_SKY.cl

What this procedure dose: Wavelength calibration either by CAL lines or OH sky lines

This is a batch (CL) script doing wavecalib-related IRAF tasks (identify, reidentify, fitcoord, transform) for FOCAS

Standard fitting parameters (like, fitting order) is pre-defined within the task


After bias-subtraction, and flat-fielding by fspecred.pro

Before sky subtraction by fskysub.cl

IRAF parameters setup

Data input: Object.fits, CAL.fits (Output files of fspecred.pro)

CAL.fits will not be used for FWAVECALIB_SKY.cl
In this case, sky lines in Object.fits would be used instead.

Data output: Object_wc.fits (wavelength-calibrated Object files)

Usage:

Startup CL script

Identify CAL lines, or sky lines using standard IRAF identify procedure.

See here and here for line identification reference.

Re-identify

Non-interactive procedure. Wait

Fitcoord

Fit the coordinate using standard fitcoord procedure.

Transform

Non-interactive procedure. Wait.
