Frequently Asked Questions¶
How do I update marvin?¶
pip install --upgrade sdss-marvin. Marvin will get updated to the latest
version, along with all the dependencies. If you want to update marvin but keep other
packages in their currrent versions, do
pip install --upgrade --upgrade-strategy only-if-needed sdss-marvin. This will only
update dependencies if marvin does need it.
How do report a bug/request a feature?¶
As Marvin is on Github, we recommend submitting a Github Issue.
Why does galaxy X have a thumbnail that is all black?¶
Some galaxies in MaNGA are special targets from one of our ancillary science programs. These targets might end up being outside the main SDSS footprint. In these cases, the optical image retrieved using the Image Cutout Service will return a blank black field.
