WARNING: No Cannon-based data is provided in DR16.
In DR14/15 we supplied an alternate set of stellar parameters and abundances as derived from a data-driven method called the Cannon (Ness et al. 2015, Casey et al. 2016) trained on the calibrated stellar parameters and abundances from ASPCAP.
For DR16, we have chosen not to do this because evaluation compared to parameters and abundances as derived by optical high-resolution studies showed no improvement in accuracy as compared to the values from ASPCAP. However, we encourage anyone interested in testing different analysis-techniques on our data to pursue the use of this tool.
You may visit the DR15 webpages for documentation on how the Cannon was implemented and released in the past. Note that this will take you to a previous data release.
