# Working with radial velocity data (thejoker.data)¶

## Introduction¶

The Joker provides a class for storing and passing around radial velocity measurements for individual targets.

TODO: note that default behavior is to subtract out minimum time, so phi0 will be phase at minimum time.

## API¶

### thejoker.data Module¶

#### Classes¶

 RVData(t, rv[, ivar, stddev, metadata, t0]) Time-domain radial velocity measurements for a single target.
