Column | Fieldname | Unit | Description |
---|---|---|---|
1 | DataScan | - | Filename of spectral scan. Filename is of the form SFYYHHMM.DDD, with
|
2 | Volume | - | Volume of published data |
3 | TimeB | - | Date
and Time at start of item 2 of a solar spectral irradiance scan. Date
and time refer to Greenwich Mean Time and are encoded into a single
number where the integer part is the day number relative to January 1,
1900 (day 1 corresponds to 1/1/1900). The fractional part is the time
of day. (For example, the fractional part multiplied with 24 gives the
hour of the measurement).
Note: When the file is decoded by Microsoft Excel, the date value will automatically be translated into a correct date/time string, if the box "1904 date system" of the "Tools -> Options -> Calculation"-menu is unchecked. |
