Abstract for MTS:
This is a simple FORS2 long slit spectroscopy program to be carried out in bad seeing conditions of two bright elliptical galaxies NGC 4594 and NGC 3923. Because the slit is 2" wide and the goal is absorption line spectroscopy, the "through slit" image is not strictly required for the acquisition of the data. For the excution of the obs, simply point and acquire the spectrum at the slit position.
Please follow the user priority for the execution of the science Obs.
The slit on the finding charts is indicated by the white thick line.
For NGC 4594 there are 5 OBs. In these OBs the slits are aligned and parallel to the minor axis of the galaxy at PA=0.
For NGC 3923 there are 6 OBs. In 3 OBs, the slit is either aligned or parallel to the galaxy major axis at PA = 45, and in the other three, the slit is either aligned or parallel to the galaxy minor axis at PA=135.
Waiver request was submitted for OBs longer than an hour.
Special Calibration Information: the user supplied calibration OBs for the stellar templates to be executed during the morning twilight.
The OBs for the stellar templates are listed below with the apparent B magnitudes of the stars, and their spectral type:
CAL-HR5601 mB=5.4 KOIII
CAL-HD136028 mB=7.4 K5III
CAL-HR6770 mB=5.7 G8III
These calibrations can be acquired on different nights from the science OBs.
