Summary
The general philosophy is that the file type should be human readable and easy to use for both researchers and developers. We should support multiple readers to ingest various catalog formats into the PyCSEP codebase.
The catalog will initially be defined as an ASCII .csv format where each row corresponds to a single event. This file will have the following headers:
longitude, latitude, M, epoch_time (time in millisecond since Unix epoch in GMT), depth,
+x-offset, +y-offset, catalog_id, event_id
longitude: longitude in decimal degrees [-180,180]
latitude: latitude in decimal degrees [-90,90]
M: magnitude arbitrary units
epoch_time: time in milliseconds since unix epoch [-inf, inf]
depth: hypocenter depth in (km) [0, inf]
+x-offset: east-west offset from lon/lat in (m) [-inf, inf]
>
+y-offset: north-south offset from lon/lat in (m) [inf,inf]
catalog_id: indicates type of catalog
- observed: -1
- simulated: [0,n_cat-1]
event_id: used to indentify events beyond the basic properties
- comcat: eg., 'ci0000000'
- ucerf3: eg., fault-system solution of supraseismogenic
This format can be easily extended to additional file types, including more advanced storage types like HDF5 or databases.
