P73-504: Probing the Fast X-ray Transients by Einstein Probe

PI: Johan P. U. Fynbo, Dong Xu



ALFOSC/StanCam + NOTCam ToO program with override status

ToO triggers have override status.

This program has 5 hours of RRM mode with ALFOSC.

The OB generator will be used to request all observations.
The OBs will automatically appear in the OB queue and OB generated scripts will be automatically placed in the directory ~/scripts/73-504/.

For the observer:

Go to the directory
  cd ~/scripts/73-504
List the available scripts
  ls -lrt
and execute the OB generated scripts requested.
If you cannot find the corresponding observing script, please (re-)compile it from the Queue interface.

In the case of NOTCam, make sure that differential skyflats are obtained for the camera and filter setup that is requested.

Remember to fill the RRM or ToO or SoftToO tracking logs of this program.
