Estimated Total Execution Time (hours, including overheads)
General Description
This program aims at determining precise radial-velocities for a set
of stars known to follow well defined solar-type magnetic cycles.
The goal is to follow this stars for several years, and to check if there are
radial-velocity variations during the cycle, that could be
missinterpreted as due to the presence of a long-period giant planet.
In the OB's, multiple exposures are done to avoid CCD saturation (conservative
seeing of 0.4'' considered); long total exposures are needed to
average the noise induced by stellar acoustic modes.
Given the brightness of the targets, no finding charts are needed.

Critical Observing Condition Constraints
Time-Critical Aspects
At the time the OBs were submitted we had not yet the final schedule of
the observations. Usually we ask for 5 different and separate runs, since
the goal is to follow the stars in the long term.
We have thus decided to schedule observations in 5 different runs (A-E). The
OBs are names accordingly. For each run, the following dates were tentatively
used to check for the observability of the objects:
25 Abril - Run A
25 May - Run B
25 June - Run C
25 July - Run D
25 September - Run E
These dates were chosen since they correspond to moments of guaranteed time
observations with HARPS, and thus it is imaginable that the current
service mode runs will be executed at the same moment.
In case the final schedulle is very different from this please let us know
so that we can change the OBs.

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 ?
