Seismogram files

AIMBAT uses SAC files as input. Before adding files to an AIMBAT project please ensure the following header fields are set correctly in all files:

• Seismogram begin time (SAC header B).
• Seismogram reference time (KZTIME) and date (KZDATE).
• Station name (KSTNM), latitude (STLA) and longitude STLO).
• Event origin time (O), latitude (EVLA) and longitude (EVLO).

To detect any potential problems with the data before importing them into AIMBAT, you can use the AIMBAT cli:

$ aimbat checkdata *.BHZ
sacfile_01.BHZ: ✓✓✓
sacfile_02.BHZ: ✓✓✓
sacfile_03.BHZ: ✓✓✓
sacfile_04.BHZ: ✓✓✓
sacfile_05.BHZ: ✓✓✓
sacfile_06.BHZ: ✓✓✓
sacfile_07.BHZ: ✓✓✓
sacfile_08.BHZ: ✓✓✓
sacfile_09.BHZ: ✓✓✓
sacfile_10.BHZ: ✓✓✓
sacfile_11.BHZ: ✓✓✓
...
sacfile_NN.BHZ: ✓✓✓

The seismogram files can be stored in an arbitrary directory (i.e. they do not necessarily need to be stored together with an AIMBAT project file).
