                       TRFXform7Tuple

7-Tuple `(tx, ty, tz, s, sx, sy, sz)` of conversion parameters with translations `tx`, `ty` and `tz` in `milli-meter`, scale `s` in `ppb` and rates `sx`, `sy` and `sz` in `milli-arc-seconds-per-year`.

Note: The parameters are also named as `(Tx, Ty, Tz, D, Rx, Ry, Rz)` or `(T1, T2, T3, D, R1, R2, R3)`.

Method Details

### __add__ (self, other) (Addition operator) |
Return the sum of this and an other TRFXform7Tuple. Overrides: tuple.__add__

### __mul__ (self, factor) |
x*n Overrides: tuple.__mul__ (inherited documentation)

### inverse (self, name='') |
Return the inverse of this transform. Arguments: `name` - Optional name (`str`). Returns: Inverse (TransformXform).

Property Details

### isunity Is this a `unity, identidy` transform (`bool`). Get method: isunity(self) - Is this a `unity, identidy` transform (`bool`). Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.
