In bvsonawane/photosynthesis: Leaf phosynthesis: Data cleaning, computations and C3 and C4 modelling

Description

Calculate photosynthetic discrimination for C and O isotopes using 4 cycle caliberations and one licor connection. One can define upto two different combinations of 4 cycle caliberations.

Usage

cal_tdl(dat, site_line_seq_1 = c(20, 21, 22, 23, 3, 7, 8),
  site_line_seq_2 = c(20, 21, 23, 24, 3, 7, 8), licor_ref = 7,
  licor_samp = 8, L3_tot_CO2 = 365.89, L3_d13_pdb = -37.68,
  d18O_L3_raw = -20.5, L3_d18O_SMOW = 20.12655253625,
  d13pdb_mix = -40.88, d18Ovsmow_mixing_tank = 5.223019134725,
  f_other = 0.00474, Rvpdb_C = 0.0111797, f_other_o = 0.1185,
  Rvpdb_O = 0.01185, R18Osmow = 0.0020052)
