Stores distance values per band in different matrices. Saves in
different files. Doens'nt seems to work
Modified value of distFlag. Now is `5`\
Added redshift and absorption correction before fit. Changed way f dealing with flagged values in distance calc.
Added time_correct() and correct_for_absorption function + tests.
Fixed bug in call to time_correct().
Added redshift_distrib() function to plot redshift distribution of the whole sample.
