(catl_type='memb', catl_kind='mocks', hod_n=0, halotype='fof', clf_method=1, clf_seed=1235, dv=1.0, sigma_clf_c=0.1417, sample='19', type_am='mr', perf_opt=False)[source] [edit on github]¶ Prefix of the paths based on the type of catalogues and input parameters chosen.
Parameters: - catl_type : {
memb
,gal
,group
}str
, optional Type of catalog to analyze. This option is set to
memb
by default.- Options:
memb
: Analyzes the member galaxy catalogues of a group cataloggal
: Analyzes a simple galaxy cataloguegroup
: Analyzes agroup
galaxy catalogues with galaxy groups.
- catl_kind : {
data
,mocks
}str
Kind of catalogues to download. This variable is set to
mocks
by default.- Options:
data
: Downloads the SDSS DR7 real catalogues.mocks
: Downloads the synthetic catalogues of SDSS DR7.
- hod_n :
int
, optional Number of the HOD model to use. This value is set to
0
by default.- halotype : {‘so’, ‘fof’},
str
, optional Type of dark matter definition to use. This value is set to
so
by default.- Options:
so
: Spherical Overdensity halo definition.fof
: Friends-of-Friends halo definition.
- clf_method : {1, 2, 3},
int
, optional Method for assigning galaxy properties to mock galaxies. This variable dictates how galaxies are assigned luminosities or stellar masses based on their galaxy type and host halo’s mass. This variable is set to
1
by default.- Options:
1
: Independent assignment of (g-r) colour, sersic, and specific star formation rate (logssfr
)2
: (g-r) colour dictates active/passive designation and draws values independently.3
: (g-r) colour dictates active/passive designation, and assigns other galaxy properties for that given galaxy.
- clf_seed :
int
, optional Value of the random seed used for the conditional luminosity function. This variable is set to
1235
default.- dv :
float
, optional Value for the
velocity bias
parameter. It is the difference between the galaxy and matter velocity profiles.\[dv = \frac{v_{g} - v_{c}}{v_{m} - v_{c}}\]where \(v_g\) is the galaxy’s velocity; \(v_m\), the matter velocity.
- sigma_clf_c :
float
, optional Value of the scatter in log(L) for central galaxies, when being assigned during the
conditional luminosity function
(CLF). This variable is set to0.1417
by default.- sample : {‘18’, ‘19’, ‘20’, ‘21’},
str
, optional Luminosity of the SDSS volume-limited sample to analyze. This variable is set to
'19'
by default.- Options:
'18'
: \(M_r = 18\) volume-limited sample'19'
: \(M_r = 19\) volume-limited sample'20'
: \(M_r = 20\) volume-limited sample'21'
: \(M_r = 21\) volume-limited sample
- type_am : {‘mr’, ‘mstar’},
str
, optional Type of Abundance matching used in the catalogue. This variable is set to
'mr'
by default.- Options:
'mr'
: Luminosity-based abundance matching used'mstar'
: Stellar-mass-based abundance matching used.
- perf_opt :
bool
, optional If
True
, it chooses to analyze theperfect
version of the synthetic galaxy/group galaxy catalogues. Otherwise, it downloads the catalogues with group-finding errors included. This variable is set toFalse
by default.
Returns: - catl_prefix :
str
Prefix of the paths based on the type of catalogues and input parameters.
