9 Differentiation between correction with or without an F-Theta objective.
The following applies: Parameter = 10 × P
Obj
+ P
Typ
with
• P
Obj
= 0: Correction without F-Theta objective
P
Obj
= 1: Correction with F-Theta objective
• If correction with F-Theta objective:
P
Typ
= 0.0: without distortion data
P
Typ
= 1.0: with F-Theta’s F-stop progression condition
P
Typ
= 2.0: with image height table
10 Indicator for the source of the correction file.
The following applies: Parameter = 1000 × P
Orig
+ P
Ver
with
• P
Orig
= 10000: originally calculated file
P
Orig
= 20000: converted from ctb file
P
Orig
= 30000: reconstructed from txt file
By manipulating a correction file using correction programs available from SCANLAB,
P
Orig
is increased by 1 in each case.
– P
Ver
= Version number of the program used to create the correction file
11 Information about the inverse table.
The following applies: Parameter = P
Exist
+ 2 × P
Calc
with
• P
Exist
= 1.0: valid inverse table is present
P
Exist
= 0.0: no valid inverse table present
• If valid inverse table is present:
P
Calc
= 0: inverse table calculated ab initio
P
Calc
= 1: inverse table numerically calculated
12 Angle calibration of the scan system.
Mechanical angle deflection in [± °] at 96% of the maximum control.
13 Code for the scan head geometry used for the calculation (for internal use only), for example,
• = –1.0: unknown geometry (for example, for a table converted from a ctb file)
• = 0.0: standard geometry
14 Indicator for whether an additional protective window has been taken into account.
The following applies: Parameter = 1,000,000 × P
T
+ 1,000 × P
I
with
• P
T
= Protective window thickness in mm (max. 2 decimal places)
• P
I
= Refraction index (max. 3 decimal places)
Example: The value 3,521,450.0 corresponds to a protective window thickness of 3.52 mm
and a refraction index of 1.450.
15 Indicator for whether the Image Field size has been limited in the correction file.
• = 0.0: without field size limit
• = 2.0: with field size limit
(a) Numbering according get_table_para and get_head_para.
