File "hitran_cia2012_adapted.xml.gz" contains HITRAN 2011 CIA data
adapted for ARTS calculations.

Besides the conversion to ARTS XML format, some changes have
been made. See below for list of changes and comments.

"N2-CIA-N2-0":   Rototranslational band.
"N2-CIA-N2-1":   Fundamental band. For this, two different HITRAN datasets have been fused.
"N2-CIA-H2-0":   
"N2-CIA-CH4-0":   
"H2-CIA-H2-0":   
"H2-CIA-He-0":   
"H2-CIA-CH4-0":   
"H2-CIA-H-0":    Only for high temperatures (above 1000 K)
"He-CIA-H-0":    Only for high temperatures (above 1500 K)
"O2-CIA-O2-0":   Higher dataset numbers not included (they are in the UV/Vis).
("O2-CIA-N2-0":  Not included! Only UV/Vis.)
("O2-CIA-CO2-0": Not included! Only UV/Vis.)
"CO2-CIA-CO2-0": Only up to 250 cm^-1. HITRAN themselves recommend caution.
"CH4-CIA-CH4-0":   
"CH4-CIA-Ar-0":

Valid frequency and temperature ranges are as follows:

Log of Changes:

N2-N2: Merged the two high-frequency datasets.

O2-O2: Kick out UV/Vis datasets

CO2-CO2: This is only the self continuum of CO2. The CO2-air continuum
	 has strong features above 250 cm^-1 that
	 are present in CKD_MT but missing here.
	 HITRAN data generally looks weird. It is only in the
	 alternative folder, and in the paper they basically recommend
	 not to use it. ==> No changes, but usage not recommended.

O2-N2, O2-CO2: UV/Vis only, remove.
