25 can be queried via eg this tool's search function.

27 REQUIRMENTS OF THE DOWNLOADED FILES 

28  

29 The downloaded files must be in a specific format for this method to succeed. The columns are the 

30 important things; one can filter the results as one desires using Splatalogue, but the particular columns must be present as described 

31 below. The columns which must be present in the downloaded file in this exact order are: "Species", "NRAO Recommended", "Chemical Name", 

32 "Freq in GHz", "Resolved QNs", "CDMS/JPL Intensity", "Sij^2; (D2)", 

33 "Log10 (Aij)", "EL (K)", "EU (K)", "Linelist". In order to get these columns in this order, one should 

34 select exactly the following items on the Splatalogue search interface. Under "Specify Ranges" one should select "GHz" for the frequency unit. 

35 Under "Line Strength Display" select exactly "CDMS/JPL Intensity", 

36 "Sij u2", and "Aij". Under "Energy Levels", one should select exactly "Elower (K)" and "Eupper (K)". Under "Miscellaneous", one should 

37 select exactly "Display Ordered Frequency ONLY" and "Display NRAO Recommended Frequencies". One should then initiate the search and on 

38 the resulting page, one should select the Tab Field Separator and then export the list. The resulting list should be in the proper 

39 format for importing into CASA.

76 for radio recombination lines (rrls), one must specify to include rrls in the specified frequency range in the output. In this case,
