Instructions from the PI
Dear NOT observer and staff.
This is a set of instructions for NOT monitoring programme P68-509
(PI:Håkon Dahle), scheduled for service observations. The purpose is to monitor
three of the five currently known gravitationally lensed quasars where the
lens is a galaxy cluster. The main purpose of the observations is to use the
light curves to make time delay measurements between multiple lensed quasar
images in order to estimate the value of the Hubble constant. We will also
determine the level of microlensing in each lens system.
The target information and the observing strategy are reported below.
Please let us know whether you carried out these observations.
Thank you!
Best regards,
Håkon Dahle
------------
For the "monitoring" observations use
the script indicated by the OB.
Calibrations:
For calibration we request:
- A set of three twilight flats for the SDSS g' filter
- alfosc-calibs
Available scripts
Go to the directory
cd ~/scripts/68-509
For these observations use the appropriate script for the date, complie the
OB if needed.
