General Description
This program has as objective the measurement of the jitter of active
stars in the infra-red. To do so stars of different spectral type are measured and
their values compared with the ones from RV standards. In order to calculate relative
RVs in a meaningful way, the OBs must be done sequentially, in the order: GJ803
-- HD10700 (RV std) -- HD203019 -- HD20794 (RV std) -- HD17925, and with no gaps
in between.
By proceeding this way the observations can be done in a monolythic block observable
at low airmass during the months of August and September. There are 8 sets of observation
(numbered from 0 to 7) and only one set (once again, with the 5 targets in the aforementioned
sequence) can be done per night. The 8 sets should be done in consecutive nights
but, even though recomended, this is not absolutely necessary.
This program is particullarly well suited for bad seeing periods, as the loss of
expendable photons is more than compensated by the reduced guiding and photocenter
errors.
I would kindly ask the astronomer on duty to inform me upon data acquisition for
this program, so that the targets can be followed with the CORALIE spectrograph
in the same period.

Critical Observing Condition Constraints
This program should be done at the worst seeing conditions possible, in
order to reduce photocenter-induced errors. Still, aware that the astronomer on
duty has to manipulate programs following diverse constraints, I leave this as a
recomendation more than an absolute need.
Time-Critical Aspects
Special Execution Requirements
In order to calculate relative RVs in a meaningful way, the OBs must be
done sequentially, in the order: GJ803 -- HD10700 (RV std) -- HD203019 -- HD20794
(RV std) -- HD17925, and with no gaps in between. There are 8 sets of observation
(numbered from 0 to 7) and only one set (once again, with the 5 targets in the aforementioned
sequence) can be done per night. The 8 sets should be done in consecutive nights
but, even though recomended, this is not absolutely necessary.
Special Calibration Information
(The same as special execution requirements.) In order to calculate relative
RVs in a meaningful way, the OBs must be done sequentially, in the order: GJ803
-- HD10700 (RV std) -- HD203019 -- HD20794 (RV std) -- HD17925, and with no gaps
in between. There are 8 sets of observation (numbered from 0 to 7) and only one
set (once again, with the 5 targets in the aforementioned sequence) can be done
per night. The 8 sets should be done in consecutive nights but, even though recomended,
this is not absolutely necessary.
ToO Information
ToO Activators List
Do the README file and the instrument comments of the telluric stars
OBs include the required S/N/pixel of the spectrum of the telluric star, its spectral
type and allowed spectral range?
Do any OBs include wavelength or flatfield calibrations?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If the slit viewer guide star is different from the target, are the RA
and DEC offsets accurate to within 0.05 arcsec and do they take into account the
relative proper motion between the two objects?
If you have preferences which OBs should be executed first for objects
at similar RA, did you make use of the User Priority field in the OBs?
