The program should be easy to execute, no non-standard calibrations/instrument
settings are required, and the targets are bright for the VLT.
The observations can be started during twilight and should be finished before 23:30
local time, since the air mass will then exceed 2.0. The time needed for the program
was actually overestimated in the proposal, for this reason another target (S719)
was added with lower priority. In case there is time left, this object can be observed
to fill the three hours asked for.
Since the targets are highly variable, there is no sense of giving a B and R band
magnitude. In any case, the objects are cool and red, therefor the highest admissible
value for the B-R colour was chosen. Due to their red colour, some of the targets
might be challenging for the AO.
The telluric standard (HR 7188) should be observed twice, between science target
1 and 2, and between science target 3 and 4. There is no prefered sequence of the
science targets.
A lamp calibration should be done for each of the settings (34/-1/n, 34/-1/i, 24/1/n,
and 24/1/i), but only once. The respective template is included in the OBs of the
object M794, but may be executed at any time. An absolute wavelength calibration
is not essential, thus the error introduced by the finite grating reproducibility
is not of importance. The actual DITs and NDITs for the lamp exposures may be adapted
to the current recommended values.
