NAME:
windows
PURPOSE:
plot the spectral windows for a given element
INPUT:
Either:
(a) wavelength, spectrum (\AA,spectrum units)
(b) spectrum (assumed on standard APOGEE re-sampled wavelength grid)
(c) location ID, APOGEE ID (default loads aspcapStar, loads extension ext(=1); apStar=True loads apStar spectrum)
+element string (e.g., 'Al'); Adding 1 and 2 splits the windows into two
KEYWORDS:

OUTPUT:
plot to output
The final axes allow one to put additional labels on the plot, e.g., for adding the APOGEE ID:
bovy_plot.bovy_text(r'$\mathrm{%s}$' % '2M02420597+0837017',top_left=True)
Note that an ID (e.g., the apogee ID) and Teff, logg, metallicity, and alpha-enhancement labels can be added using the keywords label* above
