Also note e References printed in bold are surveyed while references in italics are derived e The reference naming convention is the same as in the rest of the program see chapter 4 3 Reference list e Like in the rest of the program the references are sorted by number if their name starts by a number otherwise they are sorted by name e Unused references are not listed e References with multiple names are not marked as such 5 3 Compact report type The compact report is used for a compact yet informative representation of the quality level of the project This result in reported data being structured quite differently compared to how it is structured in the program The report starts with a list of scans and references used A typical compact report page is shown in Figure 16 34 ATS Advanced Technical Solutions AB All Rights Reserved Report Name X Y Z dX dY dZ Tot Scans 130206 Avenvn gbg 080 F71 461 170 957 093 19 364 6 8 6 1 6 6 1L3 F72 439 151 969 471 18 862 7 5 0 8 8 6 ll4 Sphere4 473 730 943 444 18 640 0 7 638 15 23 16 7 Scans 130206 Avenvn sbg 082 F72 439 157 969 471 18 873 1 6 0 9 1 6 25 F71 461 265 937 086 19 369 1 6 0 9 L6 2 5 Sphere4 473 729 943 451 18 625 0 0 00 0 0 0 0 Scans 130206 Avenvn_ghg 083 P72 430 258 969 470 18 869 0 8 O35 21 3213 F71 461 164 957 087 19 373 0 8 05 Zl 23 Scans 130206 Avenvn sbg 084 P72 439 161 969 466 18 876 2 0 43 5 3 7 1 F73 415 688 1008 168 18 004 0 6
