Reference_membrane_colony_density_first_experiment

First replicate of the Infection efficiency experiment. The data was collected from the reference membranes used to measure viable spore densities during the inoculation spraying. The first column, "treatment", contains numbers giving the spore concentration in the inoculated spore suspension, spores/ml. The second column, "position" refers to position of the membrane on the infection plate so that number 1 was at one end, number 2 next to it and so on, from 1 to 5. The third column, "number" identifies the counting square used to sample the colony density, arbitrary numbering of up to two squares in the first and up to three squares in the second experiment. The fourth column, "colony", gives the number of colonies counted in the square. The fifth column, "percm", gives the density of colonies within a square, colonies/cm^2. The sixth column, "size", gives the size of a square, always "1", except for highest concentration treatment of the second experiment, cm^2. Tab delimited .txt file.
