When I use HEMCO-standalone dev/13.0.0,
HEMCO_sa_Spec.rc has removed emMW_g and MolecRatio
#ID NAME MW K0 CR PKA

but I found the SUBROUTINE Model_GetSpecies in hcoi_standalone_mod.F90 still read them

901 ! Read species ID, name, molecular weight, and Henry coefficients
902 ! K0, CR, pKa (in this order).
903 DO I = 1, 8
904
905 ! Get lower and upper index of species ID (first entry in row).
906 ! Skip all leading spaces.
907 UPP = LOW
908
909 DO WHILE( UPP == LOW .AND. LOW /= LNG )
910 LOW = LOW + 1
911 IF ( LOW > LNG ) THEN
912 WRITE(MSG,101) I, TRIM(DUM)
913 CALL HCO_Error( MSG, RC, THISLOC=LOC )
914 RETURN
915 ENDIF
916 UPP = NextCharPos( TRIM(DUM), HCO_SPC, LOW )
917 IF ( UPP < 0 ) UPP = LNG
918 ENDDO

The conflicting settings will cause errors in calculating emissions using hemco_standalone:
forrtl: severe (24): end-of-file during read, unit -5, file Internal List-Directed Read

HEMCO_Spec.rc.txt
hcoi_standalone_mod.F90.txt

So has hcoi_standalone_mod.F90 not been fix yet for retiring carbon-based units for VOCs?
Besides, should I offer species-based units offline emissions when no further use carbon-based in v13.0.0 and later version?

This is now resolved in commit 880dec3 and will be included in the GEOS-Chem 13.0.0 / HEMCO 3.0.0 release.
