This code generates simulations of the low-frequency radio sky and celestial bodies from a given landing site on the Moon. Users input landing site coordinate and desired time of observation in UTC and LOCHNESS will output the altitude/azimuth of common celestial bodies as seen from the landing site. In addition, users can supply a healpy map to LOCHNESS and it will be rotated into the landing site reference frame for the given UTC time.
If you use the algorithms or code contained in LOCHNESS, please cite (Hibbard et al?)
First, make sure that all relevant dependencies are installed properly:
You will need the following Python packages:
To clone a copy of the repository:
git clone https://github.com/CU-NESS/lochness.git
Then install the LOCHNESS package via:
cd lochness
python setup.py develop
Note that it is necessary to have the appropriate SPICE kernels downloaded (see the spicepy documentation above), including:
naif0012.tls,
de440.bsp,
pck00011.tpc,
moon_080317.tf,
moon_assoc_pa.tf,
moon_pa_de421_1900-2050.bpc.
However, for users in a hurry, we have uploaded the most relevant ones for the LOCHNESS calculations in the directory:
lochness/input/spice_kernels/
so they can be used immediately upon installation of LOCHNESS, which will download the necessary files.
These are accurate and updated as of 2023.
