Known bugs

Collapse Plugin spectral bounds don’t match selected region

Spectral bounds are off in the plugin compared to the spectrum viewer.

Specviz Unit Conversion with subset selected

Trying to convert units with a subset selected in the spectrum viewer results in error messages, but works when there is no subset selected.

The bug doesn’t happen when a subset is selected before the first conversion, but does happen when a subset is selected after the first conversion and a second conversion is applied. It doesn’t happen when no subset is selected and successive conversions are applied.

Ghost subsets and models in spectrum viewer

Mysterious extra subsets and models appear in the Specviz spectrum viewer after fitting a model. Pan/zoom and resize were also used, but it is unclear if they play a role or not in this bug.

Cubeviz Collapse and Moment Maps: Spectral bounds do not match Region selection

When trying to do a second collapse with the same spectral region, but with resized bounds: change to Region=None, resize the region, then reselect Region 1, the region bounds are correct. However, applying Collapse again, it errors out and the image viewer that contained the intial collapse goes blank.

Flashing display when data is added or removed too quickly

If data addition/removal is done too quickly, the front-end can get “desynced” from the kernel. The stopgap solution for this is to just restart the kernel or restart jupyter notebook entirely if the bug persists.

Cubeviz cube viewer colormap printed out

When changing the colormap in the Cubeviz cube viewer–>Layer–>colormap, the colormap name is printed in the cell output.

Cubeviz cube viewer contrast changes when collapsing jupyter scroll window

In order to see the full Cubeviz app in a Jupyter notebook, one can click on the side of the cell output to collapse or expand the scrollable window. This has the unintended consequence of changing the contrast of the image displayed in the Cubeviz cube viewer.

Gaussian smooth crashes after selecting smoothed data in spectrum viewer

Attempting to apply the Gaussian Smooth functionality on a spectrum that is itself the result of a previous application of Gaussian Smooth, results in an error dump.
