Estimated Total Execution Time (hours, including overheads)
General Description
This is a spectroscopic long-term monitoring of the bright Be star zeta
Tau in support
of the interferometric AMBER and polarimetric (LNA - Observatorio do Pico Dos Dias,
Brazil) observations with the aim to detect and model the global (density wave)
oscillations in the circumstellar disk of the star.
All five OBs are identical.
Waiver Requests
Critical Observing Condition Constraints
No strict observing conditions. Because the star is very bright, the Feros
observations can be executed almost under any conditions, including thick clouds,
provided that the integration time is adjusted appropriately.
Time-Critical Aspects
It is very desirable that
- the OB zeta Tau-Nov is executed simultaneously with our polarimetric observations
(Oct 13/14 and 14/15) or only 1 day earlier
- the OBs zeta Tau-Dec-1 and zeta Tau-Dec-2 are executed simultaneously with the
AMBER observations on Dec 11/12, 2006, one at the beginning and the second in the
end of the night in order to test the possible activity of the star and fast variations
in the inner part of the disk during the interferometric observations.
- the OB zeta Tau-Nov is executed at the very beginning of the service window starting
in the end of November (Nov 28 -30)
- the OBs zeta Tau-Jan) completes the spectroscopic monitoring in January and its
execution is not very time critical (Jan 10 - 31).

Is this a Pre-imaging run ?
Pre-imaging Requirements
Source(s) of Pre-imaging
Pre-imaging sources not listed above
Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
Did you set 'New Preset' flag in all acquisition templates to 'True'?
If you use any lamp, did you check that it should never be left on at
the end of any OB?
