gradient_position_data.txt
position data from the light gradient experiment.
t - day of the experiment, t=0 is the start position the animals were inserted at, t=1 is the first recorded attached position
"lane" columns - position of the individuals along the gradient in [cm]. 0 cm equate 2 muE m^-2 s^-1 , 60 cm equate 102 2 muE m^-2 s^-1)
"_sym" or "_apo" at the end of the column name indicate symbiotic or aposymbiotic animals, respectively

####
light gradient function
The light gradient is described by the function y = -3.523e-05 x^4 + 3.866e-03 x^3 - 9.246e-02 x^2 + 8.986e-01 x + 1.736
x - distance in gradient in [cm]
y - PAR in [muE m^-2 s^-1]

raw_o2_concentrations
outputfiles of Pyro Oxygen Logger
O2 concentrations are found under "Oxygen" in [mg L^-1]
Ch1-3 are replicates, Ch4 is a control in all files
which replicates correspond to which channel is indicated in the filenames
filenames contain the respective light level, 2 files prer light level (2 x (3 replicates + 1 control))
t[s] - time in seconds, used for our analysis

####
raw_o2_rates.txt
raw O2 rates as generated by LoLinR, alpha = 0.4, data thinned by 5
PAR - light level
animal - animal identifier, corresponds to animal identifier in the symbiont count data. Seawater controls indicated as c1 and c2.
volume - volume of incubation chamber [in mL]
alpha - alpha parameter of LoLinR
thinning factor - data thinning factor (function thinData() , LoLinR)
o2_rate - raw Oxygen rate as computed by LolinR in [mg animal^-1 s^-1 L^-1]

####
raw_symbiont_counts.txt
raw algal symbiont count data per animal
PAR - light level
animal - animal identifier, corresponds to animal identifier in the O2 data
volume - volume of sample homogenate [in mL]
technical_replicate - technical replicate identifier of cell count measurements
symbiont_cell - zooxanthellae cells [in 10^6 cells per mL]
