This page collects representative MapLines workflows.

Single-spectrum fit

Fit an emission-line complex in a one-dimensional spectrum.

from MapLines.tools.line_fit import line_fit_single

line_fit_single(
    file1="spectrum.fits",
    file_out="fit_result",
    file_out2="fit_parameters",
    name_out2="single_example",
    config_lines="line_prop.yml",
    z=0.01,
    lA1=6500.0,
    lA2=6600.0
)

IFU cube analysis

Fit a spectral cube spaxel by spaxel.

from MapLines.tools.line_fit import line_fit

line_fit(
    file1="cube.fits",
    file2="aux.fits",
    file3="mask.fits",
    file_out="cube_model",
    file_out2="cube_params",
    name_out2="ifu_example",
    config_lines="line_prop.yml",
    z=0.01
)

BPT diagnostics

Build and visualize a BPT classification map from fitted products.

import MapLines.tools.plot_tools as pt

pt.plot_bpt_map2(
    fileR="red_fit.fits.gz",
    fileB="blue_fit.fits.gz",
    name="galaxy_name",
    path="outputs/"
)

Region extraction

Extract spectra or values from DS9-defined apertures and paths.

import MapLines.tools.tools as tools

wave, spec = tools.extract_spec(
    filename="cube.fits",
    ra="10:27:00.0",
    dec="+17:49:00.0",
    rad=1.5
)

Map visualization

Display parameter maps and derived products.

import MapLines.tools.plot_tools as pt

pt.plot_single_map(
    file="Ha_map.fits.gz",
    valmax=100,
    valmin=1,
    tit="Halpha Flux",
    lab="[10^{-16} erg/s/cm^2/arcsec^2]"
)
