MOXSI Line Catalogue#

Start building a catalogue of the lines we want to target for diagnostics in our bandpass. We have a reduced table from the proposal but there are reasons to believe it is not complete and/or the wavelengths may not be as accurate as we would like. The goal here is to use the most recent version of CHIANTI to build a catalogue of the lines we believe will be important for both active regions and flares.

Lines from Original Proposal#

The following lines are those from Table 2 of the CubIXSS proposal. These are the lines I’ve been using to label my spectra thus far.

[2]:

line_ids = [
    ('Fe XVIII',14.21*u.angstrom),  # also targeted by MaGIXS
    ('Fe XVII', 15.01*u.angstrom),  # also targeted by MaGIXS
    ('Fe XVII', 16.78*u.AA),
    ('Fe XVII', 17.05*u.AA),
    ('O VII', 21.60*u.angstrom),  # also targeted by MaGIXS
    ('O VII', 21.81*u.angstrom),
    ('O VII', 22.10*u.AA),
    ('O VIII', 18.97*u.angstrom),  # also targeted by MaGIXS
    ('Fe XXV', 1.86*u.AA),
    ('Ca XIX', 3.21*u.AA),
    ('Si XIII', 6.74*u.AA),
    ('Mg XI', 9.32*u.AA),
    ('Fe XVII', 11.25*u.AA),
    ('Fe XX', 12.83*u.AA),

Line Lists from CHIANTI#

I’ve run the ch_ss GUI from CHIANTI IDL and then exported the lines identified for the $1<\lambda<70$ Å range. I’ve built two tables, one for the AR DEM and one for the extended flare DEM. I’m then combining these all into a single table by having a separate intensity column for each DEM. Then, I’m going to write this file back out that we can use as a reference when looking at model spectra.

Parse the tables produced by CHIANTI. This parsing cleans up the column names and adds some additional columns, including the intensities scaled by the abundances.

[7]:

ar_line_table = parse_chianti_line_file('../sandbox/data/moxsi_ar_lines.fits')
flare_ext_line_table = parse_chianti_line_file('../sandbox/data/moxsi_flare_ext_lines.fits')

Now, we combine these two separate tables into one, labeling the non-unique column names according to the DEM used.

unique_cols = ['max temperature',
               'only theoretical',
               'intensity (coronal)',
               'intensity (photospheric)',
               'intensity_scaled (coronal)',
               'intensity_scaled (photospheric)']
combined_line_list = astropy.table.join(
    flare_ext_line_table, ar_line_table,
    keys=[c for c in flare_ext_line_table.colnames if c not in unique_cols],
    table_names=['flare_ext', 'active_region'],
    join_type='outer'

This yields a really large line list so we want to pare it down a bit. We apply the condition that the active region or flare intensity must be above a given threshold.

The resulting line list is greatly reduced compared to the original. Let’s write our complete line list to an ASDF file which makes it really easy to load the whole table in.

We can inspect our line list a bit further in terms of the two cases we’re interested in, looking at the top AR and flare lines.

Finally, let’s make sure that our new line list at least includes all of those lines from the proposal table with approximately the same wavelength.

matching_rows = []
for row in proposal_table_2:
    is_same_ion = np.logical_and(row['element'] == reduced_line_list['element'],

    same_ion = reduced_line_list[np.where(is_same_ion)]
    i_wave = np.argmin(np.fabs(same_ion['wavelength'] - row['wavelength']))
    matching_rows.append(same_ion[i_wave])
proposal_table_2_from_line_list = astropy.table.vstack(matching_rows)
