Description

FIXME

Functions

nc_reduced_shear_cluster_mass_new ()

NcReducedShearClusterMass *
nc_reduced_shear_cluster_mass_new (void);

This function instantiates a new object of type NcReducedShearClusterMass.

Returns

A new NcReducedShearClusterMass.

nc_reduced_shear_cluster_mass_ref ()

NcReducedShearClusterMass *
nc_reduced_shear_cluster_mass_ref (NcReducedShearClusterMass *rscm);

Increases the reference count of rscm by one.

Parameters

rscm

a NcReducedShearClusterMass

Returns

rscm .

[transfer full]

nc_reduced_shear_cluster_mass_free ()

void
nc_reduced_shear_cluster_mass_free (NcReducedShearClusterMass *rscm);

Atomically decreases the reference count of rscm by one. If the reference count drops to 0, all memory allocated by rscm is released.

Parameters

rscm

a NcReducedShearClusterMass

nc_reduced_shear_cluster_mass_clear ()

void
nc_reduced_shear_cluster_mass_clear (NcReducedShearClusterMass **rscm);

The reference count of rscm is decreased and the pointer is set to NULL.

Parameters

rscm

a NcReducedShearClusterMass

nc_reduced_shear_cluster_mass_P_z_gth_gobs ()

gdouble
nc_reduced_shear_cluster_mass_P_z_gth_gobs
                               (NcReducedShearClusterMass *rscm,

                                const gdouble z,
                                const gdouble g_th,
                                const gdouble g_obs);

Computes the probability distribution $P(g_\mathrm{obs} | g_\mathrm{th}, z)$.

Parameters

rscm	a NcReducedShearClusterMass
cosmo	a NcHICosmo
z	the redshift $z$
g_th	the computed reduced shear $g_\mathrm{th}$
g_obs	the observed reduced shear $g_\mathrm{obs}$

Returns

$P(g_\mathrm{obs} | g_\mathrm{th}, z)$

nc_reduced_shear_cluster_mass_posterior_no_shear_calibration ()

gdouble
nc_reduced_shear_cluster_mass_posterior_no_shear_calibration
                               (NcReducedShearClusterMass *rscm,
                                NcHICosmo *cosmo,
                                const gdouble z,
                                const gdouble g_obs);

Types and Values

enum NcReducedShearClusterMassParams

These parameters refers to the shear calibration, and the Voigt profile.

In particular, we consider the shear calibration as defined for STEP and STEP2 simulations: $$\hat{g}_{Teo} = (1 + m)g + c,$$ where $g$ is the reduced shear, the multiplicative bias $m$ is $$ m =\left{ \begin{array}{c l} a \frac{r_{gal}}{r_{PSF}} + b & \frac{r_{gal}}{r_{PSF}} < x_p \ b & \frac{r_{gal}}{r_{PSF}} \geq x_p \end{array}\right. $$ and $c = constant.$ $r_{gal}$ and $r_{PSF}$ are the galaxy and PSF (point spread function) sizes, respectively. See Applegate (2014).
