Vertical Velocity - High-Rate/Low-Rate (Overlaid In Plots): High-rate and low-rate vertical velocity data will be overlaid and plotted on one graph. For broadband seismometers, this will be HHZ for the high-rate channel and MHZ or LHZ for the low-rate channel depending on the requested time range. For short period seismometers, this will be a high-rate channel of EHZ and a low-rate channel of MHZ or LHZ.

High-Rate Vertical Velocity: High-rate vertical velocity data will be plotted on one graph. For broadband Seismometers, this will be channel HHZ. For short period seismometers, this will be channels EHZ.

Oceans 2.0 API filterdpo_seismometerChannel=HHZ

Low-Rate Vertical Velocity: Low-Rate vertical velocity data will be plotted on one graph. For broadband and short period seismometers, this will be channel MHZ or LHZ depending on the requested time range.

High-Rate Velocity - All Three Components: All high-rate velocity data will be plotted on separate graphs. For broadband seismometers this will be channels HHZ, HHN, HHE. For short period seismometers this will be channels EHZ, EHN, EHE.

Low-Rate Velocity - All Three Components: All low-rate velocity data will be plotted on separate graphs. For broadband and short period seismometers this will be channels MHZ, MHN and MHE or LHZ, LHN and LHE.

All Channels - High-Rate/Low-Rate Channels (Overlaid In Plots): The All Channels Option will plot all available channels for the seismometer including velocity, accelerometer data, as well as pressure data. The high-rate and low-rate velocities and accelerations will be overlaid with matching orientations. If the selected output format is MAT file or miniSEED, then mass position will also be included.
