## Mapping description

The table below details where and how each variable was retrieved from the input product.

field name | mapping description
--- | ---
scan_subindex | description | the scanline and pixel dimensions are collapsed into a temporal dimension; the index of the pixel within the scanline is computed as the index on the temporal dimension modulo the number of scanlines
datetime | path | /BAND3_IRRADIANCE/STANDARD_MODE/OBSERVATIONS/time, /BAND3_IRRADIANCE/STANDARD_MODE/OBSERVATIONS/delta_time[]
description | time converted from milliseconds since a reference time (given as seconds since 2010-01-01) to seconds since 2010-01-01 (using 86400 seconds per day); the time associated with a scanline is repeated for each pixel in the scanline
orbit_index | path | /@orbit
wavelength | path | /BAND3_IRRADIANCE/STANDARD_MODE/INSTRUMENT/calibrated_wavelength[]
photon_irradiance | path | /BAND3_IRRADIANCE/STANDARD_MODE/OBSERVATIONS/irradiance[]
