# obspy.io.nordic.core

Nordic file format support for ObsPy

license: | GNU Lesser General Public License, Version 3 (https://www.gnu.org/copyleft/lesser.html)

Note

Currently does not read nor write moment tensors or focal mechanism solutions from/to Nordic files.

Note

Pick time-residuals are handled in event.origins[0].arrivals, with the arrival.pick_id linking the arrival (which contain calculated information) with the pick.resource_id (where the pick contains only physical measured information).

Public Functions

`blanksfile` | Generate an empty s-file with a populated header for a given waveform.
`nordpick` | Format picks in an `Event` to nordic.
`read_nordic` | Read a catalog of events from a Nordic formatted select file.
`read_spectral_info` | Read spectral info from an sfile.
`readheader` | Read header information from a seisan nordic format S-file.
`readwavename` | Extract the waveform filename from the s-file.
`write_select` | Function to write a catalog to a select file in nordic format.

Private Functions

Warning

Private functions are mainly for internal/developer use and their API might change without notice.

`_evmagtonor` | Switch from obspy event magnitude types to seisan syntax.
`_float_conv` | Convenience tool to convert from string to float.
`_get_headline` |
`_int_conv` | Convenience tool to convert from string to integer.
`_is_sfile` | Basic test of whether the file is nordic format or not.
`_nortoevmag` | Switch from nordic type magnitude notation to obspy event magnitudes.
`_read_picks` | Internal pick reader.
`_read_spectral_info` | Internal spectral reader.
`_readheader` | Internal header reader.
`_readwavename` | Internal wave-name reader.
`_str_conv` | Convenience tool to convert a number, either float or int into a string.
`_write_nordic` | Write an `Event` to a nordic formatted s-file.

Exceptions

`NordicParsingError` | Internal general error for IO operations in obspy.core.io.nordic.
