[Product Definition Template 4.153] Some octet numbers are incorrect #350

Introduction

As I was updating the NOAA/NCEP GRIB2 documentation to reflect the recent WMO V36 GRIB2 update, I noticed that some of the octet numbers in product definition template 4.153 are mislabeled. This can be corrected in the next semi-annual update.

Amendment details

These are the octet numbers I am referring to:

21-23	4	Forecast time in units defined by octet 20	(see Note 2)	                        111
24	        1	Type of first fixed surface	                        (see Code table 4.5)		4.5		
25	        1	Scale factor of first fixed surface
26-30	4	Scaled value of first fixed surface

I think they should be updated to these:

21-24	4	Forecast time in units defined by octet 20	(see Note 2)	                        111
25	        1	Type of first fixed surface	                        (see Code table 4.5)		4.5		
26	        1	Scale factor of first fixed surface
27-30	4	Scaled value of first fixed surface
