Information for Visiting Astronomers
Before your run
- Getting ready
With your ESO User Portal username and password you get access to the webletters detailing your observing runs. This username and password you will also later need to prepare your OBs on Paranal using the P2PP3 tool. Have your run number (e.g. 084.A-0123(A)) and username and password ready - you will use them all the time.
If you have not yet done so, please, provide your travel information on the Visiting Astronomer travel form.
- Start working
Get acquainted with your instrument. The links on the left-side menu bar will take you to the various instruments web pages. Please be sure to read the documentation in there. In particular, some of the instruments have some specific instructions and recommendations for visiting astronomers, accessible through the "visitor" link on each of the instrument web page.
P2PP3: In order to prepare the observations, you will need the Phase 2 Preparation Program version 3. You should have a look at the Phase 2 page even for visitor runs. Note that your OBs do NOT have to be checked in the database in advance.
Targets and backup: Make sure you have enough targets for the whole night. In case you need more to fill the night, additional targets must be requested and approved in advance. Similarly, you should have a backup program in case the conditions do not permit your main program to be executed. In particular, keep in mind that strong wind often comes from the North, so backup targets to the South should be prepared. Additional targets, backup targets and change of set-up must be requested well in advance using this procedure.
- When arriving at Paranal
You will have two nights on Paranal prior to the start of your run, in order to finalize your observation strategy and your observation blocks together with your operation specialist / support astronomer and your night astronomer.
You are kindly requested to stay in the observatory Residencia while you are preparing your observations and until the beginning of your run. Visitors are not allowed to drive on the mountain, transportation to the telescope is arranged with your support astronomer.
From the Residencia you have access to a Linux PC for the preparation of your observation blocks (see Computing). If you have any problem with the PC, please contact your day-time support astronomer. These PCs have all the preparation software installed, as well as the SciSoft suite of astronomical software. See the SciSoft Computer Page for details and instructions, and the Data Reduction Software page for information on what is available where and details about the configuration.
- OB Preparation
Please make sure to discuss your observing strategy with your supporting operation specialist or daytime astronomer. For very specific questions or special details, you can request to discuss them with the night astronomer.
Some specific remarks:
- FORSes: the fims files are saved in the directory .fims/SET whereas you can put your image in .fims/PREP.
- FORSes: please do not edit the FIMS files. This may produce problems at the execution. You can have a look at them inside p2pp (command edit).
- FORS observations: fill in as soon as possible the Setup Form which will be handed to you by the introducing astronomer. In any case, set-up forms must be given before 9:00LT the day before your observing night.
- Before moving to the control room, "export" all your OBs to the p2pp-impex directory for transfer and notify your Daytime Support Astronomer.
- The Observations!
On the days of your observations, you will be driven up by one of the support astronomers. He will also assist you to transfer the OBs from the machine on which you prepared them to the system at the telescope.
Once at the telescope, you will have many things to do -- refer to this separate page "At the Telescope", also linked from the left menu.
You can copy your data to your personal laptop. Connect the laptop to the wireless network ESO_VA in the control room (password provided by the night astronomer). Then push the data from the offline machine to your laptop, using e.g. scp or rsync. You can also copy the data to your visas account and transfer them to your laptop from there.
We have two printers, laser1 (B/W) and colorlaser (colour) in the control room that can be used from any computer in the control room. They are accessed directly via the internet. If you want to set them up on your laptop, use JetDirect and you will need the actual IP-address, which is found written on each printer. The setup tool depends on the system you are running (e.g. use printtool for fedora <=5; system-config-printer for fedora 6, preference menu - printer for mac).
After your run
Your data will be made available immediately on the ESO archive via the User Portal. The CalSelector option will allow you to automatically include all necessary associated calibrations into your data package. You will get via email a copy of the electronic night report.
- End-of-mission report
Please send us an End-of-Mission Report after you have completed your observing run.
- Pipeline and Quality Control
The "Quality Control" group of the Data Flow Operation Department performs many tests and measurements on all the data coming form Paranal. Many results, such as noise, gain, zero points, color terms, etc, are avaible from their page
