* utils: Add ds.py with function "dictlist_to_dataframe()"Aaron LI2017-08-031-0/+82
| | | | | | | This function convert a list of dictionaries created by e.g., GalaxyClusters._simulate_halos() to be a Pandas DataFrame. Signed-off-by: Aaron LI <aly@aaronly.me>
* clusters/emission.py: Make "F()" be class method, fixing memory hole!Aaron LI2017-08-011-22/+35
| | | | | | | | | | | For unknown reason! Each instance of "SynchrotronEmission" will cost ~5 MiB memory when interpolating the kernel function cached as "self._F_interp", which won't be collected/freed by GC, for UNKNOWN reason! Therefore, make the method "F()" be class-wide, to avoid the memory hole! Signed-off-by: Aaron LI <aly@aaronly.me>

* clusters/emission.py: Fix units/dimensions problemAaron LI2017-07-261-1/+2
| | | | | | | | | | | NOTE: Since we just substitute ``p`` (electron momentum) for ``γ`` (electron Lorentz factor), i.e., N = int_p n(p) dp = int_γ n(γ) dγ , therefore the coefficient ``sqrt(3) e^3 B / (m c^2)`` does NOT need modification (e.g., multiply an extra ``m c``)!
