Summary of Parameters

IMage

(file) Name of image for input. This should be a file containing continua spectra.

ARC_OPTS

(char) Enter arc fit option:

NEW (N)

set up a new wavelength calibration

REPEAT (R)

Iterate on previous calibration

CLONE (C)

CLone a previous calibration

OLD (O)

Correct using previous results

OUtput

(file) Name of output file. File to contain corrected data.

XStart

(int) analysis lower limit. The data between the limits xstart and xend is extracted and the resultant spectrum is used to locate the lines.

XEnd

(int) analysis upper limit. The data between the limits xstart and xend is extracted and the resultant spectrum is used to locate the lines.

XBlock

(int) Enter averaging width in channels. Each window is of this width (except perhaps the final one).

ITeration

(short) New value of iteration

LEvel

(float) Level of edge of tooth

ORder

(int) order for polynomial fitting This is for the continuity correction of the data.

MAXLines

(int) Maximum number of lines to allow room for This must be greater than or equal to the number of lines fitted, so room should be allowed in case any more are to be added later.

CLfile

(file) Name of image for cloning from. This should be a file containing an comb spectrum.

TOls

(char) For use in batch only

KEEP_ITT

(key) keep iteration files?

QUick

(key) Centroid rather than fit Gaussians?

PRFits

(key) Print out details of fitting

PLOtcorr

(key) Plot correction?
