artes.in

Here you find a list with all possible keywords for the input file that is required by ARTES. This file can have any name but is called artes.in throughout the documentation.

Important

There are no spaces allowed between the keywords and values.

----------------------------------------------------------------------
* General

* Write log file (on) or screen output (off)
general:log=off

* Send e-mail when finished
general:email=

* Use random seed (on/off)
general:random=on

----------------------------------------------------------------------
* Photons

* Photon source (star, planet)
photon:source=star

* Photon stopping parameter (0-1)
photon:fstop=1d-5

* Minimum photon energy (0 < minimum <= 1) relative to the start energy (= 1)
* A photon is stopped if the energy gets smaller
photon:minimum=1d-20

* Weight cell luminosity, equal photons emitted from all cells (on/off)
* Only used when "photon:source=planet"
photon:weight=off

* Photon scattering (on/off)
photon:scattering=on

* Thermal photon emission direction (isotropic/biased)
* Only used when "photon:source=planet"
photon:emission=isotropic

* Biased emission asymmetry parameter (0 <= bias < 1)
* Only used when "photon:source=planet" and "photon:emission=biased"
photon:bias=0.8

* Modified random walk parameter
* walk > 0 -> on
* walk < 0 -> off
photon:walk=-1

* Photon number for debugging
* This parameter can be ignored
photon:number=0

----------------------------------------------------------------------
* Star (only required when "photon:source=star")

* Stellar temperature (K)
star:temperature=5800

* Stellar radius (R_sun)
star:radius=1

* Stellar direction (deg)
* 0 <= star:theta <= 180
* 0 <= star:phi < 360
star:theta=90
star:phi=0

----------------------------------------------------------------------
* Planet

* Surface albedo (black=0, lambert=1)
planet:albedo=0

* Oblateness (0-1)
planet:oblateness=0

* Orbital radius (au)
planet:orbit=5

* Circumplanetary ring (on/off)
planet:ring=off

* Minimum distance to the next cell boundary that is considered [m]
planet:grid=1d-6

* Maximum optical depth, tau > 0
* tau < 0, recommended: tau=30 -> reflected, tau=5 -> emission
planet:tau=-1

----------------------------------------------------------------------
* Detector

* Observation mode (image, spectrum, phase)
detector:type=image

* Polar and azimuthal direction towards the detector (deg)
* 0 <= detector:theta <= 180
* 0 <= detector:phi < 360
detector:theta=90
detector:phi=90

* Number of detector pixels in both dimensions
detector:pixel=25

* Distance between planet and detector (pc)
detector:distance=10

* Rotation angle of the detector (deg)
* 0 < detector:angle < 360
* angle < 0 -> off
detector:angle=-1

----------------------------------------------------------------------
* Output

* Output errors for debugging (on/off)
output:debug=off

* Track the global photon movement (on/off)
output:global=off

* Track the latitudinal photon movement (on/off)
output:latitudinal=off
