Roadmap of SunXSpex

Functionalities

Needs: Database of Intensities as a function of temperature at all line energies. (Stored at SSW/packages/xray/SSWDB/CHIANTI/chianti_lines_1_10_v71.sav)

Must: Match these to data bins for a given temperature. Figure emissivity of lines given temp and abundance and sum into each energy bin.

Sub-Functionalities

• Validate input energy binning
• Load Dbase for easy retrieval if not loaded already
• Deal with abundances
  • Load global choice of abund. e.g. coronal, photospheric
  • Handle/include variations to those, e.g. due to FIP.
• Identify lines of interest based on input energy range.
• Compute emissivity for every temp., for every line.
• Associate every line with a pair of data bins.
• Formulate weighting of those two bins that maintains line centroid's energy.
• Now every output energy bin has a set of lines associated with it. For each bin, add up emissivity to produce final spectrum.

Note, this can be rewritten to enable output of the different spectral components.

  • chianti_kev.pro
  • chianti_kev_lines.pro
    • mk_contiguous (perhaps can be done differently in Python, e.g. by requiring N+1 length input of bin edges like output of numpy histogram.)
    • chianti_kev_common_load (perhaps can be done differently in Python)
    • xr_rd_abundance
    • chianti_kev_getp (Could be part of chianti_kev_lines.pro)
  • brem_49.pro ?

• f_thick2.pro
  • Currently waiting for Richard to update IDL version before planning Python version.
