Parameter | Description |
---|---|
Rootflag | Boolean. True if this entity is the coordinate system root. |
x, y, z | Cartesian. Internally the coordinates are stored as picometer (pm) values in a signed 64-bit integer. These coordinates are relative to the parent coordinates (i.e., for collections, the parent collection; for datasets, the containing collection). |
Scale | Multiplication factor for Cartesian coordinates; for better readability, e.g., set the scale to 1000 if nanometer values should be displayed. |
dx, dy, dz | Estimated standard error of Cartesian coordinates (in pm). |
t | Time stamp in seconds since 1.1.1904 00:00:00 Universal Time ignoring leap seconds. The time stamp is represented in a 128-bit fixed-point number with a 64-bit radix. The first 64 bits are a signed integer for the seconds, the second 64 bits are unsigned fractions of a second. |
dt | Estimated standard error of the time stamp (in fractional seconds). |
Description | Description of the coordinate system (string); field to provide additional, ‘human readable’ information. |
