The objective of this page is to make both WFI and FEROS Visiting and
Support Astronomers aware of what is required/expected of them in the
case of Target of Opportunity observations [ToOs] at the MPG/ESO-2.20m
The observatory wide policy with respect to ToOs is spelt out here.
In all cases what is set out in that page supersedes and takes precedence
over anything in this page which might contridict that page.
Required information FROM Triggerers
Since FEROS is now a p2pp/OB compliant instrument, simply
complete the ToO trigger form
following following the instructions at that page.
Information FOR ToO Triggerers
All standard observing modes are available to ToO programmes. Standard
calibrations are provided as part of the Calibration Plan. Additional
calibrations must be requested in the trigger form. Additional
calibrations that require execution during the night will be charged
the time required to execute them. Please note that requests like
"Please observe a nice RV standard" will NOT
All data will be provided via the standard FTP archive procedures.
Performing ToO observations
The following provides practical
instructions for the observer at the telescope carrying out the
observations and need not be read by the Triggerer.
FEROS ToO observations are the
responisibility of and will normally be carried out by the 2.20m
Support/Service Mode Astronomer.
Start up FEROS Observing Environment and Initialise DRS
Normally the 2.20m daytime TIO will startup the FEROS Observing
Environment and initialise the DRS. That procedure is detailed here.
Once complete the system is ready for FEROS observations, however WFI
observations can also be made without problem.
The standard, established observing procedures should be followed for
ToO observations. Fetch the OBs to Bob from OT (or in exceptional
circumstances p2pp), and execute as usual.
calibration observations of a spectrophotometric standard must be
carried out in addition to any non-standard
All relevant data must be ftped to archive.eso.org

ferosMkToODir on w2p2off can be used to prepare a
directory containing ALL the data related to the ToO including
calibrations. Normally the script can be run as soon as the Science
observations have been completed (i.e. before the end of night
calibrations). Data transfer can thus begin asap. Rerun the script the
following afternoon to add the end of night calibrations (if any) to
directory and then complete the ftp transfer by sending the end of
data. To use the ferosMkToODir script:
Open an xterminal on w2p2off as user e2p2ops.
ferosMkToODir "<Prog-ID>" -d <yyyy-mm-dd> Note: the quotes (") around the <Prog-ID>
argument are necessary. The complete ID is needed, e.g. "71.D-0192(A)"
After assembling the data package, the script will automatically guide
you through uploading the data to the ESO Archive ftp server.
End of Night
Follow the standard Endo of Night procedures detailed here, i.e. run CALOB.
Repeat the above procedure for the Data Package in order to send
the morning calibrations. In the final step when ncftp will ask if you
overwrite the log file type O (to over write). When it prompts if you
want to overwrite the next file, type S! in order to skip over all the
other files and get on with transferring only the data not already
When complete, finally you are done (except for updating the normal ToO
files and Remedy ticket and notifying, Shift Leader etc...)
