Spectrum [contents] [index] [procedure]

spectra ""

List of file names of spectra to analyze. @filename indicates list should come from file filename. As of version 1.3, apertures of multispec spectrum files can be entered as numbers, lists, or ranges enclosed in brackets after each file name in the list or file.

specnum 0

If this is nonzero and spectra contains a single file name, this is a range of apertures in a multispec file in which emission lines will be fit. This number is ignored if a spectrum number is specified using brackets. Wavelength dispersion information is read from APNUMn or the WCS keywords. Velocity information is read from APVELn and saved in APVELn and APVEMn.

specband 0

If this is nonzero, it is the band in the multispec file(s) specified by spectra in which emission lines will be fit. Wavelength dispersion information is read from APNUMn, where n is the aperture specified by specnum or the WCS keywords. Velocity information is read from APVELn and saved in APVELn and APVEMn. (New in version 2.0)

skyband 0

Sky spectrum band if this is a multispec spectrum which contains a removed sky spectrum. This is used to compute error.

specdir "./"

Directory containing spectrum to be analyzed. This part of the pathname is not printed at the top of the page, and is assumed to be the same for all spectra listed in the spectra parameter.

Process Spectrum [contents] [index]

output ""

Output file name

bands ""

Name of file containing bandpasses over which to compute equivalent widths

banddir ""

Name of directory containing bandpass file

bandfilt no

If yes, filter names follow wavelength limits in bandpass file

bandcont no

Continuum names precede wavelength limits in bandpass file

bindim 0

Minimum number of rows in bin by one spectrum

normalize no

Normalize the bandpass response (yes or no)

fitcont yes

If yes, fit continuum instead of averaging points (yes or no)

netflux no

Compute net flux from emission region instead of eqwidth

byexp no

Convert to counts per second (exposure normalization)

bypix no

Convert to counts per row (spatial normalization)

torest yes

If yes, measure flux at rest wavelength instead of observed wavelengths. Shift band wavelengths using VELOCITY keyword.

mag no

Output results in magnitudes?

magzero 0.

Magnitude zero point

device "stdgraph"

Display device

plot_pobj no

Plot the raw object data

int_obj no

Interact with plot of raw object data

plot_fitcont no

Plot the continuum fit to the data

plot_contsub no

Plot the continuum-subtracted data

int_contsub no

Interact with plot of continuum-subtracted data

nsmooth 0

Number of times to 1-2-1 smooth plotted spectra

report_mode 1

Report mode (1 standard 2 line names in headings)

nsum 1

Number of pixels to sum across dispersion

hardcopy no

Automatic hardcopy of results (yes or no)

plotter "stdplot"

Hardcopy output device

debug no

Print debugging info (yes or no)

verbose yes

If yes, a header describing equivalent width parameters is sent to output.
