This page and subdirectories contain all of the pointings for exposures taken as part of the Pan-STARRS NEO search.

They are organized by Observing Cycle (OC), which is a number assigned to lunation from full-moon to full-moon. Specifically, the ones on this page were generated from USNO Circular 169 on 2020-06-19, and rounded down to MJD date for display purposes.

The index for the coverage is here: https://neo.ifa.hawaii.edu/coverage

The folder and file structure is:
<OC>/coverage-<observatory>-<MJD>.json.gz
For example:
314/coverage-PS1-60846.json.gz

We do not create a file for dates where we took no data. So there will be MJD gaps.

The contents of the gzipped json file match the schema expected by the MPC (to whom we also submit the pointings):
https://minorplanetcenter.net/pointings/#fields

It is comprised of a list of json objects, with each object being similar to:

{
    "action": "exposed",
    "surveyExpName": "o60844h0080o",
    "mode": "survey",
    "mpcCode": "F52",
    "time": "2025-06-18T06:45:45.400",
    "duration": "45.0",
    "center":
    [
        209.999683,
        -15.05000
    ],
    "limit": 22.0,
    "fieldDiam": 3.2,
    "filter": "Pw"
}
