verbose
Print lots of output to screen regarding status of calculation?
Default:
True
progress_bar
Use python progress-bar (if installed)?
Default:
True
initial_redshift
Initial redshift of calculation, i.e., the redshift at which we switch from cosmological initial conditions to the ARES solver.
Default: 60
final_redshift
Calculation stops at this redshift.
Default: 5
track_extrema
Track 21-cm extrema in real-time. These are referred to as turning points B (first stars), C (first black holes), and D (beginning of Epoch of Reionization) in works such as Burns et al. (2012), Harker et al. (2012), and Mirocha et al. (2013).
Default:
False
stop
If
track_extrema==True
, setstop
to'B'
,'C'
, or'D'
to terminate the calculation once the given turning point is reached.Default:
None
stop_xavg
You can also stop a calculation once a given mean ionized fraction is reached. For instance, if you'd like to terminate once the IGM is half ionized, set
stop_xavg=0.5
.Default: 0.99999
time_units
Internal units for time.
Default: 3.15576 × 1013 s (i.e., 1 Myr)
initial_timestep
Time-step at
initial_redshift
.Default: 0.01 [
time_units
]max_dt
Maximum allowed time-step.
Default: 1 [
time_units
]max_dz
Maximum allowed redshift-step.
Default: None
dtDataDump
Save all physical quantities at this time cadence.
Default: 1 [
time_units
]dzDataDump
Save all physical quantities at this redshift cadence.
Default: None
epsilon_dt
Maximum fractional change in quantities of interest in a single time-step. Quantities of interest are listed in
restricted_timestep
(see below).Default: 0.01
restricted_timestep
A list containing quantities use to restrict the time-step via
epsilon_dt
. Options:'ions'
: restrict time-step based on rate of change in ion fractions.'neutrals'
: restrict time-step based on rate of change in neutral fractions.'electrons'
: restrict time-step based on rate of change in electron density.'temperature'
: restrict time-step based on rate of change in temperature.'hubble'
: restrict time-step based on Hubble expansion.
Default:
['ions', 'electrons', 'temperature']
tau_redshift_bins
Number of points to use when discretizing the IGM optical depth in redshift.
Default:
None
tau_prefix
Path to directory on disk where optical depth tables are stored. Set this if you keep optical depth tables stored in a place other than the
$ARES
environment variable!Default:
None
load_sed
Same as
tau_prefix
, but refers to lookup tables for complex spectral energy distributions (such as SIMPL) which are expensive to calculate.Default:
False
sed_prefix
Location of SED tables
Default:
None
