The binary file format is as follows
v_ini as a signed integer (number of initial vibrational levels)
v_fin as a signed integer (number of final vibrational levels)
T_int as a signed integer (number of temperature steps)
T_ini as a signed integer (initial temperature)
T_stp as a signed integer (temperature step)
T_fin as a signed integer (final temperature)
K(v_ini,v_fin,T_int) as a single precision float
for the case of V-V-T transitions:
v_ini as a signed integer (number of initial vibrational levels)
T_int as a signed integer (number of temperature steps)
T_ini as a signed integer (initial temperature)
T_stp as a signed integer (temperature step)
T_fin as a signed integer (final temperature)
K(v_ini,T_int) as a single precision float
