ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSION8.9.5.15 Field 9.140: M1 delta information / DINThis optional field shall consist of one subfield for each delta present in the original image.It can only appear if a value of '514' or '515' is entered in CFT of Field 9.126: M1 CBEFFinformation / CBI. Each repeating subfield consists of three information items 78 .• The first item (‘x’ coordinate / XCD) is an integer in pixel units.• The second item (‘y’ coordinate / YCD) is an integer in pixel units.• The third information item ( first angle of the delta / ANG1) is recorded in units oftwo degrees. The value shall be between 0 and 179, inclusive. This is the angleclosest to 90 degrees.8.9.5.16 Field 9.141: M1 additional delta angles / ADAThis optional field shall only appear if Field 9.140: M1 delta information / DIN isincluded in this record. 78 This field has been added to handle the two additional anglespecifications of INCITS 378 while maintaing backward compatibility with the 2007version of this standard (Traditional encoding). The subfields shall describe the samedeltas in the same order as the subfields of Field 9.140: M1 delta information / DIN.• The first information item (second angle of the delta /ANG2) is the next angleencoded in order of appearance when moving counterclockwise.• The second information item (third angle of the delta / ANG3) is the last angleencoded in order of appearance when moving counterclockwise.8.9.6 Externally defined feature setsThis standard has reserved several blocks of fields for external definition. These blocksof fields may be used in conjunction with other blocks of fields 79 .8.9.6.1 FBI / IAFIS feature setFields 9.013 through 9.030 are reserved for this block. These fields are defined in the FBI'sEFTS version 7.1 through EBTS version 9.2 but are superseded beginning with EBTS 9.3;see www.fbibiospecs.org .8.9.6.2 3M (Cogent) feature setFields 9.031 through 9.055 are reserved for this block. For information on these fields,consult 3M.78In earlier versions of this standard, only one angle was referenced; however, the 2004 and 2009 versionsof INCITS 378 standard specify three angles for each delta. The second two angles are contained in Field9.141: M1 additional delta angles / ADA.79This was allowed in the 2007 version of the standard, but not the 2008 version. This version is consistentwith the 2007 version, in allowing multiple blocks in a single record.May, 2013 DRAFT VERSION UPDATE 2013 Page 141
