Comment

gSIM_EPS

\(\rm -\)

Numeric precision of the simulation

gSIM_EPS_DRAWN

\(\rm -\)

Numeric precision of the drawn clumps (can be decreased separately, to significantly speed up calculations)

gSIM_IS_WRITE_GALPOWERSPECTRUM

\(\rm -\)

If True, write angular power spectrum of DM skymap. Find here an example Jupyter-notebook of how to display the APS output.

gSIM_IS_WRITE_ROOTFILES

\(\rm -\)

If True, write output additionally in ROOT format

gSIM_OUTPUT_DIR

\(\rm -\)

Relative or absolute path where the output files are stored. For the value -1, files will be stored in the current directory

gSIM_SEED

\(\rm -\)

Random generator seed. If set to zero, seed is chosen from computer clock

gSIM_USER_RSE

\(\rm -\)

Contrast level (in percent) above which substructures are resolved in 2D calculations. Key quantity of CLUMPY, see the first CLUMPY paper and Mean and variance
