- IMPORTANT: as of this release the gravity_image is not available using the rpm and macports installation methods. If the recipe is executed with esorex the user is informed that the recipe was compiled without yorick support and therefore is not available. If you need to use the gravity_image recipe then please use the source kit installation and install yorick together with the Yeti and OptimPack modules as described in software prerequisistes. Note that the gravity_image recipe will be deprecated in the near future.

- WARNING!! The new pipeline is meant to work with the new DPR keywords present in raw data. If you have old data (before 1st October 2017) it is highly recommended to download the data again from the ESO archive, Care has been taken in the archive to properly update the FITS headers of old data.

In order to further improve the GRAVITY Data Reduction Software we encourage all users, and in particular the PIs of an observing program to provide feedback to the ESO User Support Department mentioning GRAVITY pipeline in the subject.
