38	Notes:
39	-1	Where a code table or flag table is appropriate, “code table” or “flag table” respectively is entered in the UNITS column.
40	-2	The code tables and flag tables associated with Table B are numbered to correspond with the F, X and Y part of the table reference.
41	-3	To encode values into BUFR, the data (with units as specified in the UNITS column) must be multiplied by 10 to the power SCALE. Then subtract the REFERENCE VALUE to give the coded value found in Section 4 of the BUFR message. For example, a measured latitude is -45.76 degrees. The coarse accuracy descriptor is 0 05 002 and the encoded value is -45.76 x 102 - (-9000) = 4424.
42	-4	Where UNITS are given as CCITT IA5, data shall be coded as character data left justified within the field width indicated using CCITT International Alphabet No. 5, and blank filled to the full field width indicated.
43	-5	Classes 48 to 63 are reserved for local use; all other classes are reserved for future development.
44	-6	Entries 192 to 255 within all classes are reserved for local use.
45	-7	The use of local descriptors, as defined in Notes (5) and (6), in messages intended for non-local or international exchange is strongly discouraged. They should be kept to the barest minimum possible and must also be by-passed by the use of descriptor 2 06 YYY.
46	-8	First-order statistics are included in Table B only when they are produced, as such, by the observing system.
