Create separate instrument packs & science packs #183

Closed els1 closed 2 years ago

els1 commented 2 years ago

Currently instrument and science packs are integrated in a single pack. Need to split information set by instrument from information unique for science case.

Instrument packs should allow spectral resolution changing w/ wavelength (possible using additional files, or a resolution model). Also include min/max wavelengths for each instrument (can be by each spectral segment in an instrument too)

Requires defining intrinsic widths of lines in science pack and “spectral breaks”.

See also issue #16.

Handled by #221, #226 and #233. Important point to note: redshift is handled as follows:

  1. Lines are redshifted into the observed frame.
  2. FWHM calculated.
  3. Spectrum is de-redshifted into the rest frame.
  4. FWHM is scaled by 1/(1+z).
