Line SHEF (GOESTable() format option 6)

ASCII output using standardized SHEF codes in a format that is human readable.

  • NANs, +INFs, -INFs, and missing values show as forward slashes (/) in the output.

  • LABEL is the SHEF code (two character) parameter. Refer to https://dcs1.noaa.gov/documents/SHEF%20Codes.pdf for details on SHEF codes.

  • OFFSET is how long ago the sensor reading was made and stored in the GOESTable() data table and is reported in number of minutes.

  • INTERVAL is how often the measurement is made. This corresponds to DataInterval() of the GOES data table or the scan interval if DataInterval() is not used.

  • DATA is the data that is stored in the GOES table.

  • APPENDED OPTIONS refers to data that can be appended to the transmission.

  • SHEF Codes can be added as headers or at the beginning of lines using GOESField() option SHEF.

  • Value has a fixed width (ASCII format, width, precision, and range).

  • Value has a fixed precision (ASCII format, width, precision, and range).

  • Value only has a leading sign when negative (–).

  • Data outside of operating range will be set to the minimum or maximum of the range.

Format of data transmitted:

: <LABEL1> <OFFSET> #<INTERVAL> <DATA1> <DATA1> ... <DATA1)>

: <LABEL2> <OFFSET> #<INTERVAL> <DATA2> <DATA2> ... <DATA2> ...

: <LABEL(N)> <OFFSET> #<INTERVAL> <DATA(N)> <DATA(N)> ... <DATA(N)>

 

Example output with explanation:

GoesTable() Fields_Scan_Order = TRUE, Newest_First=FALSE, Format = 6

GoesField() Decimation = 4, Precision = 3, Width = 5, SHEF set to VB and TA
