pleiades.sammy.io.card_formats.inp03_constants module

Card Set 3 (Physical Constants) for SAMMY INP files.

This module provides the Card03 class for parsing and generating the physical constants line in SAMMY input files. This card appears after the element information and defines temperature, flight path, and resolution parameters.

Format specification (Card Set 3 - Physical Constants):: The line contains five floating-point values with variable spacing: - TEMP: Temperature (K) - FPL: Flight path length (m) - DELTAL: Spread in flight-path length (m) - DELTAG: Gaussian resolution width (μs) - DELTAE: e-folding width of exponential resolution (μs)
