X-SHOOTER p2 Tutorial
This tutorial provides a step-by-step example of the preparation of a set of OBs with XSHOOTER at the ESO/VLT. The specifics of this tutorial pertain to the preparation of OBs for Period 101 onward. Please note that all the figures shown below can be clicked on to get higher resolution versions.
Please refer to the main p2 webpage (and the items in the menu bar on the left of that page) for a general overview of p2 and generic instructions on the preparation of Observing Blocks (OB). Please also follow the link to the p2 ObsPrep Tutorial for explanations on what can be done with the ObsPrep tab of p2, including interactive planning of blind offset and observing offsets (e.g., generic offsets, nod-on-slit), uploading of user provided background images which are also used to create the instrument-compliant Finding Charts with the p2fc Tab (see here).
Screenshots for the tutorials were made using the demo mode of p2, but should not differ in any way from one's experience in preparing your own OBs under your run.
The Phase 2 process begins when you receive a communication of the ESO Observing Programmes Office (OPO) communicating to you that the allocation of time for the coming period has finalized and that the results can be consulted in the corresponding Web page. You follow the instructions given by ESO and find that time was allocated to your run with X-Shooter. Therefore, you decide to start preparing your Phase 2 material. First, you collect all the necessary documentation:
- The XSHOOTER User Manual.
- The VLT Service Mode instructions.
- The documentation to the help section about p2 referred to above.
Observations at the VLT are performed in terms of Observing Block (OB), which represents the basic observational unit. As such, astronomers specify their programmes in terms of OBs, which contain all the necessary information to obtain a single observation. Observations with X-Shooter are therefore performed through dedicated OBs that contain both general and X-Shooter specific information. In what follows we concentrate on the main X-Shooter specific information required to construct an OB.
The links from this page will showcase some typical examples of how one can create OBs for observations with X-Shooter:
