A dataset of total spectral reflectance and total spectral transmittance expressed as fractions of one from the upper surface of a leaf of an Arabidopsis thaliana 'Ler' rosette.
Format
Datasets stored as object_spct, reflector_spct and
filter_spct objects, containing transmittance and reflectance
data.
An object of class reflector_spct (inherits from generic_spct, tbl_df, tbl, data.frame) with 1750 rows and 2 columns.
An object of class filter_spct (inherits from generic_spct, tbl_df, tbl, data.frame) with 1753 rows and 2 columns.
An object of class filter_spct (inherits from generic_spct, tbl_df, tbl, data.frame) with 2401 rows and 3 columns.
Note
Measured with a Jaz spectrometer from Ocean Optics (USA) configured with a PX Xenon lamp module and Spectroclip double integrating spheres.
