# constructor

### Description

the method constructs an object from a function a timerange where it is valid and a format

### Arguments

`map` |
a function of one argument (time) |

`starttime` |
the point in time from which map is a valid representation |

`endtime` |
the point in time until which map is a valid representation |

`lag` |
a scalar describing the time lag. Positive Values shift the argument of the interpolation function forward in time. (retard its effect) |

`format` |
a string that specifies the format used to represent the atmospheric fraction. Possible values are "Delta14C" which is the default or "afn" the Absolute Fraction Normal representation |
