2015 on-sky tests

GRACES observed a small set of science targets in preparation of the 2015B semester. We distribute the data through this page for immediate public access. The analysis and first science results will be presented here as soon as they come. 

In the following table, the first column shows the field of view overplotted with the shadow of the GRACES cassette. The red circle represents the position and the size of the science fiber. A compass is plotted in red. The arrow points to the North, and the line to the East. Succinct information about the target is given in the second column.

 

To get access to the raw data of a selected target, please click on "download raw data" in the "Obsevations" column. Associate bias and cals are also linked.

 

All the data have been reduced using the pipeline OPERA and can be found HERE.

 

For any quetion or comment, please contact the GRACES team (Andre-Nicolas Chene, Percy Gomez and Michael Lundquist).
