python3-synphot 1.3.0-1build1 (s390x binary) in ubuntu noble

 Synphot simulates photometric data and spectra, observed or otherwise.
 It can incorporate external filters, spectra, and data. One can also use
 a pre-defined standard star (Vega), bandpass, or extinction law.
 Furthermore, it allows one to:
 .
  * Construct complicated composite spectra using different models.
  * Simulate observations.
  * Compute photometric properties such as count rate, effective
    wavelength, and effective stimulus.
  * Manipulate a spectrum; e.g., applying redshift or normalize it to a
    given flux value in a given bandpass.
  * Sample a spectrum at given wavelengths.
  * Plot a quick-view of a spectrum.
  * Perform repetitive operations such as simulating the observations of
    multiple type of sources through multiple bandpasses.
