Terminology: source - a unique source name. obsid - a unique observation identifier: source_MJD{.4f} obsrec - a unique observation/hardware identifier: _LO_CNODE Obsrec file - the filename holding the obsrec information (generally .npz) experiment - a session looking at sources (typically within an MJD day or two) obsinfo - a file containing information on obsids for a given experiment: obsinfo_MJD.json

Observing Recipe (most ingredients missing at the moment...)

The focus right now is to observe the Starlink Direct-to-Cell (DTC) satellites.

• 1 Need to find and set up the satellites. This is currently interactive. The main problem is that there ARE SO MANY!

Set up the planning tool from with ipython

from obsnerd import onp_plan plan = onp_plan.Plan() The line below will look for satellite names containing 'satname' and find all tracks starting now and lasting 8 hours. Try satname='1112' plan.get_tracks(satname='some-search-string', start='now', duration=8 * 60) plan.choose_tracks() Is you want to continue, plan.proc_tracks()

Now put that ods file into '/opt/mnt/share/ods_rados/ods_rados.json'

• 2 Run the observation: aoctkuser.py --enable-rados then hit the Observe button

• 3 Copy the data into local npz files along with the obsinfo file $ on_gen_dump.py ? $ on_gen_dump.py
