sta

Base Entity | Station_Datalogger_PChannel
Attribute Name | sta
Logical Rolename |
ColumnName | sta

Attribute Name | net
Logical Rolename |
ColumnName | net
RoleName |
Definition | Unique network identifier. This character string is the name of a seismic network
Note |

data_nb

Base Entity | Station_Datalogger_PChannel
Attribute Name | data_nb
Logical Rolename |
ColumnName | data_nb
RoleName |
Definition | This attribute represents the datalogger number
Note |

pchannel_nb

Base Entity | Station_Datalogger_PChannel
Attribute Name | pchannel_nb
Logical Rolename |
ColumnName | pchannel_nb

Definition | This attribute denotes a physical channel
Note |

ondate

Base Entity | Station_Datalogger_PChannel
Attribute Name | ondate
Logical Rolename |
ColumnName | ondate
RoleName |
Definition | This attribute denotes the start date
Note |

board_type

Base Entity | Station_Datalogger_PChannel
Attribute Name | board_type
Logical Rolename |
ColumnName | board_type
RoleName |
Definition | This attribute describes the board type on the datalogger where the physical channel resides. Regular seismic channels are usually on a primary board. Auxiliary channels (internal temperature, external power, …) are usually on an auxiliary board. A value of external is used to represent a digitizer that is not part of the datalogger (for example an embedded digitizer in a digital pressure sensor). A digital board is used to represent truly digital sensors which don’t actually have any digitizing stage from Volts to Counts (for example a rainfall sensor that uses a digital counter)

channel_type

Base Entity | Station_Datalogger_PChannel
Attribute Name | channel_type
Logical Rolename |
ColumnName | channel_type
RoleName |
Definition | This attribute describes the type of the input channel. An input channel is usually classified as physical when the data is digitized (velocity, acceleration, ...). An input channel is defined as synthetic when the data is not derived directly from a sensor (clock frequency, available telemetry buffer channel, clock quality, ...)

Base Entity | Station_Datalogger_PChannel
Attribute Name | seed_io
Logical Rolename |
ColumnName | seed_io
RoleName |
Definition | This attribute represents the SEED instrument and orientation
Note |

nb_lchannel

Base Entity | Station_Datalogger_PChannel
Attribute Name | nb_lchannel
Logical Rolename |
ColumnName | nb_lchannel
RoleName |
Definition | This attribute denotes the number of logical channels of a datalogger
Note |
