Makefile

## MAKEFILE FOR RascalC. This compiles the grid_covariance.cpp file into the ./cov exececutable.

CFLAGS = -g -O3 -Wall -MMD
CXXFLAGS = -O3 -Wall -MMD -DOPENMP -DLEGENDRE_MIX -DJACKKNIFE -DPRINTPERCENTS
#-DOPENMP  # use this to run multi-threaded with OPENMP
#-DPERIODIC # use this to enable periodic behavior
#-DLEGENDRE # use this to compute 2PCF covariances in Legendre bins (original mode, corresponding to direct accumulation into multipoles from pair counts)
#-DLEGENDRE_MIX # also compute 2PCF covariances in Legendre bins, but in other, "mixed" mode, corresponding to projection of s,µ bins into multipoles
# without either of the two Legendre flags above, the covariance is computed in s,µ bins
#-DJACKKNIFE # use this to compute (r,mu)-space 2PCF covariances and jackknife covariances. Incompatible with -DLEGENDRE but works with -DLEGENDRE_MIX
#-DTHREE_PCF # use this to compute 3PCF autocovariances
#-DPRINTPERCENTS # use this to print percentage of progress in each loop. This can be a lot of output
