- Several routines for the calibration and detection of spatially-resolved sources have been included: `remove_starlight`, `remove_systematics`, and `detection_map` (thanks ricolandman!)
- The `obs_nodding_irregular` method has been added for processing data with an irregular nodding scheme (thanks ricolandman!)
- The `obs_staring` method has been added for processing data obtained in staring mode (thanks DGonzalezPicos!)
- The `extraction_required` parameter has been added to the `obs_nodding` routines for faster processing
- The `util` module has been included for utility functions. For example,`load_bt_settl_template` fetches a BT-Settl spectrum that can be used with `detection_map` (thanks ricolandman!)
- Many small improvements to the overall code and documentation
