Closes https://github.com/ros-perception/perception_pcl/issues/434 This is in analogy to https://github.com/ros-perception/perception_pcl/pull/437 and fixes https://github.com/ros-perception/perception_pcl/issues/434 but for ros2. I haven't tested it locally but if it passes the tests, it should be working as...

This pull request would fix https://github.com/ros-perception/perception_pcl/issues/434 on melodic. I adjusted the tests to require the fields to be sorted. In that way the test failed with the original code, but...

PointCloud2 fields not always sorted by offset

3

Some ROS `sensor_msgs/PointCloud2` messages created with the functions defined in [plc_conversion.h](https://github.com/ros-perception/perception_pcl/blob/ros2/pcl_conversions/include/pcl_conversions/pcl_conversions.h) will not have the `fields` attribute sorted by offset. I don't think that is a documented requirement, so the...

Convertion to Euler angles missing

2

I don't see a method that allows to extract the [Euler Angles](https://en.wikipedia.org/wiki/Euler_angles) or the [Aircraft principle axes](https://en.wikipedia.org/wiki/Aircraft_principal_axes) (roll, pitch, yaw). The equations are straight forward (see https://en.wikipedia.org/wiki/Conversion_between_quaternions_and_Euler_angles). @KieranWynn if you...

### Describe your issue. I just did a bit of benchmarking and `scipy.spatial.transform.Rotation.apply` is quite slow. It turned out the reason for this is that `numpy.einsum` is quite a bit...

XCOM doesn't understand scientific notation

2

If one provides mixtures with scientific notation for the fractional content, xcom seems to not be processing it correctly and becquerel throws an error: ``` bq.tools.fetch_xcom_data(['N 7.8e-1', 'O2 2.2e-1'], e_range_kev=[1,...

Precision issues of isotope_qty

4

The isotope quantity module does two things that are not great for numerical precision: It subtracts two very large numbers or multiplies very large numbers with very small once. It...

Fitter.custom_plot fails if roi is not defined

I currently get this error: ``` becquerel/core/fitting.py in custom_plot(self, title, savefname, title_fontsize, title_fontweight, residual_type, **kwargs) 913 param_name, v, e, np.abs(e / v)) 914 # Add info about the ROI and...
