Basics¶
Note
We will update and reorganise the opacity calculators by Release 2.0. Meanwhile, use LPF when the number of lines is less than ~ a few hundred. For larger numbers, consider to use MODIT or a more experimetal calculator PreMODIT. MODIT is limited by a device memory limits while while PreMODIT has no such limitation. Therefore, if you want to for instance, million to billion lines, use PreMODIT.
Simple Usage¶
Cross Section using Various Opacity Calculators¶
- Computing CO cross section using HITRAN (opacity calculator = LPF)
- Computing CO cross section using ExoMol (opacity calculator = LPF)
- Cross Section for Many Lines using PreMODIT
- Comparing HITEMP and ExoMol
- Cross Section for Many Lines using MODIT
- Cross section computation using the Discrete Integral Transform (DIT) for rapid spectral synthesis
