 ===== Format of the ''lin'' File =====
+line 1-NLINE [12|3, freeform]: QN, FREQ, ERR, WT
+  * QN = 12 integer field of quantum numbers. Interpreted in a multiple I3 format as the quantum numbers for the line (upper quanta first, followed immediately by lower quanta). Unused fields can be used for annotation. The entire field is printed in file.fit
+  * FREQ = frequency in MHz or cm<sup>-1</sup>
+  * ERR = experimental error.
+> NOTE: Minus sign means that the frequency and error are in units of cm<sup>–1</sup>. FREQ and ERR will be converted internally to units of MHz.
+  * WT = relative weight of line within a blend **(normalized to unity by program)**. Not needed for unblended lines. If WT is not specifically given in the line file, **1/n** will be used by the program if **n** is the number of blended lines at the same frequency and following successively.
+> NOTES: If an end-of-file is encountered before all the lines are read in, NLINE is set to the number read to that point. If successive lines have the same frequency, the lines will be treated as a blend and derivatives will be averaged using WT/ERR. Any lines with format errors will be ignored.
+The freeform input begins in column 37 and extends to the end of the line. See the notes at the end of the
+next section for more on the freeform input.
