High-Resolution Molecular Hydrgogen Optical Depth Templates

/templates

H2/HI optical depth templates in the FITS format.

/pro

IDL prcoedures for creating the templates locally

/data

I have adopted the atomic and molecular hydrogen/deuterium data implemented the Meudon PDR code, available here. A brief explanation on the data format is below. Additional details can be found in PXDR_INITIAL.f90 found in the Meudon PDR source code).

  • H2 data

    • uvh2b29.dat : Lyman Bands (B-X) : 1st electronic state X -> 2nd electronic state B

    • uvh2c20.dat : Werner Bands (C-X) : 1st electronic state X -> 3rd electronic state C

      • c1: Index
      • c2: 1=Lyman; 2=Werner
      • c3: lower vibrational level (nvl)
      • c4: lower rotational level (njl)
      • c5: upper vibrational level (nvu)
      • c6: upper rotational level - lower rotational level (nju-njl)
        • R: C6=1
        • Q: c6=0
        • P: c6=-1
      • c7: f=oscillator strength
      • c8: wavelength (Angstrom)
      • c9: gamma=inverse radiative lifetime of upper level (s-1)
      • c10: dissociation probability of upper level

    • The transition label can be created:

    bandname c5-c3 R/P/Q abs(c6)

    • g_nj:

    if (j mod 2) eq 0 then g_nj=2nj+1
    if (j mod 2) eq 1 then g_nj=3    (2*nj+1)

  • HD data

    • uvhd.data : Lyman/Werner Bands (B-X/C-X)

      • c1: 1=Lyman; 2=Werner
      • c2: lower vibrational level (nvl)
      • c3: lower rotational level (njl)
      • c4: upper vibrational level (nvu)
      • c5: - (nvu-nvl)
      • c6: f=oscillator strength
      • c7: wavelength (Angstrom)
      • c8: dummy
      • c9: gamma
      • c11: dummy
      • c12: dummy

    • The transition label can be created:

    bandname c4-c2 R/P/Q abs(c5)

    • g_nj:

    if (j mod 2) eq 0 then g_nj=2nj+1
    if (j mod 2) eq 1 then g_nj=3    (2*nj+1)

  • HI/DI data

    • uvh.dat : HI data

    • uvd.dat : DI data

      • c1: higher level - lower level,n=1
      • c2: f
      • c3: wavelength (A)
      • c4: gamma
      • c5: dummy
