Abstract for MTS:
This is a UVES/RED programme on Venus.
Observations are possibly going to take place during twilight.
According to the PI, observations can be pushed until the sun is at -7 degrees.
ACCQUISITION: always center the slit on the center of the disk. The OBs will then properly offset to the required position.
Note that the Position Angles have to be changed according to the Ephemeris File.
Due to the fact that Venus is setting quickly, only one OB per night will be observable.
The PI asks to use the secondary guiding. Due to the nature of the target, the night
astronomer should also check visually the slit centering in the Central Meridian OBs and report in the NR possible object drifts.
STD: The PI has submitted one STD OB (283961, CAL_VENUS). This OB should be executed immediately after 266503 (i.e. in PHO conditions). The standard star is Feige 67. The PI has used the UVES ETC to set the exposure time. He kindly asks the NA to check for saturation.
Note that the PI has provided a daytime CAL OB to calibrate his _expfree_ data.
