* clusters/halo: Support use the previously dumped halos raw dataAaron LI2017-10-193-1/+26
| | | | | | Add option "use_dump_halos_data" to control whether to just use the previously dumped halos data, therefore, the radio emissions at additional frequencies can be simply calculated.

|
* clusters/halo: Rewrite halos catalog and raw data saveAaron LI2017-10-192-18/+50
| | | | | Replace option "halos_dumpfile" with "halos_catalog_outfile", and use option "dump_halos_data" to control whether to dump the raw data.
* clusters: "catalog_outfile" is requiredAaron LI2017-10-192-3/+3
|
* clusters/halo: Improve time step determination a bitAaron LI2017-10-192-3/+6

|
* clusters: Update radio halo radius estimationAaron LI2017-10-182-23/+25
| | | | | | | | | The simulated radio halo is assumed to have a radius of the falling sub-cluster; while previously it is assumed to be 1/4 of the virial radius of the merged cluster. The new estimation can agree better with the currently observed radio halos, which generally have a angular diameter size of ~2-7 [arcmin].
* utils/units.py: add "rad2arcmin" and some cleanup/simplificationsAaron LI2017-10-181-16/+20
|

* clusters/emission: Assume electron pitch angle be pi/2Aaron LI2017-09-201-23/+17
| | | | And some cleanup and small changes
* clusters/emission: Rewrite synchrotron kernel functionAaron LI2017-09-201-9/+38
| | | | | | | | | | | Add asymptotic functions to calculate the values beyond the interpolation bounds (e.g., <1e-3 and >10), otherwise, the calculated synchrotron emissivity is overestimated at the higher frequencies. By rewrite this synchrotron kernel function, the calculated results is consistent with the theoretical/analytical results, e.g., the synchrotron radiation of a population of electrons of power-law index n is also a power-law with index (n-1)/2.
* clusters: Add option "use_output_catalog" to continue halo simulationAaron LI2017-09-033-4/+36

| | | | | | | NOTE: The cluster number (especially the bright ones) may be rather small within a sky patch. This ``boost`` config option increase the expected cluster number by a specified times, for better testing purpose.
