## Descriptions

`ACCESS_FORMAT` &mdash; Format of the file.

`CAVEATS`  &mdash; Information which may be important in the avoidance of the misuse of the resource, for instance the assumptions or limitations on data processing, modeling or inversions.

`Channel_ID`  &mdash; `0` = CHANNEL A,  `1` = CHANNEL B.

`Data_coordinates`  &mdash; Coordinate system used for observed magnetic field vector. "Other" means that an instrument-specific coordinate system is used.

`Data_Cycle`  &mdash; Data cycle sequence number.

`Data_Level`  &mdash;  `L1B`.

`Data_product`  &mdash;  Type of data product. It shall use the ISTP format "PREFIX>Suffix" (e.g., `"HIST1D>1D histogram"`). 

`DATAPRODUCT_TYPE`  &mdash; High level scientific organization of the data.

`Data_resolution`  &mdash; Typical resolution of data values. 

`Data_Revision`  &mdash; Revision sequence number.

`Data_sampling_type`  &mdash; What kind of time bin for averaging or sampling is used to obtain data values.

`Dataset_ID`  &mdash; Data set identifier.

`Data_type_2`  &mdash; Type of observed vector values, e.g., `"Absolute field"`, `"Variation"`. 

`D_conversion_factor`  &mdash; Factor used to convert the unit of D-component from degree to nT.

`D_unit`  &mdash; Physical unit of the D-component of the geomagnetic field. 

`Elevation`  &mdash; Elevation of the location of station. 

`Free_field`  &mdash; Description of the free field in the filename. It shall use the ISTP format "PREFIX>Suffix" (e.g., `"NORM>Normal mode"`), where the value of the prefix shall correspond to the "free" field in the file naming convention.

`Geographic_coordinates`  &mdash; What kind of geographic coordinate system is used for the following latitude and longitude. Usually either of geodetic or geographic. 

`Geographic_latitude`   &mdash; Geographic or geodetic latitude of the location of station. 

`Geographic_longitude`  &mdash; Geographic or geodetic longitude of the location of station. 

`Geomagnetic_coordinates`  &mdash; What kind of geomagnetic coordinate system and what epoch and time are used for the following geomagnetic coordinate values. 

`Geomagnetic_latitude`  &mdash; Geomagnetic latitude of the location of station. 

`Geomagnetic_longitude`  &mdash; Geomagnetic longitude of the location of station. 

`Job_ID`  &mdash; Process job identifier.

`K9_limit`  &mdash; Threshold of K-index for K = 9. (for WDC data).

`Known_problems`  &mdash; Known problems regarding the data set, such as data glitches and gaps.

`Last_obs_Count_In_File`  &mdash; Identifies the number of packets in the current science observation type.

`LEVEL`  &mdash; Data processing level as defined in the Solar Orbiter conventions. It shall use the ISTP format "PREFIX>Suffix" (e.g., `"L1>Level 1 data processing"`), where the value of the prefix shall correspond to the "level" field in the file naming convention.

`L_value`  &mdash; (Dipole) L value of the location of station.

`Magnetometer_type`  &mdash; Type of magnetometer instrument. Usually `"Fluxgate"` or `"Induction"`. 

`Maximum_PHD`  &mdash; Upper limit for the pulse height filter (typical values range from `200` to `254`).

`Minimum_PHD`  &mdash; Lower limit for the pulse height filter (typical value = `2`).

`Mirror_Hemisphere`  &mdash; Either `"N"` (north) or `"S"` (south) for the observed hemisphere.

`Number_of_channels`  &mdash; Number of channels of magnetometer. 

`OBS_ID`  &mdash; A unique identifier for the observation that is associated with the data acquisition and includes identifying information about: the SOOP; planning period; instrument; and instrument’s observation mode. The format of OBS_ID is defined in [IOR-ICD], and shall be included in the IORs delivered by the Instrument Teams to SOC.

`Observation_Complete`  &mdash; `1` if this is the last l1b file in the current observation type otherwise `0` to continue.

`Observation_end`  &mdash; The termination date of instrument operation. This is left blank if the instrument is currently in operation.

`Observation_start`  &mdash; The start date of instrument operation.
