Class

NumCosmoSNIADistCov

Description [src]

class NumCosmo.SNIADistCov : NumCosmoMath.Model
{
  /* No available fields */
}

Supernovae distance covariance between distance estimates.

This object implements the calculation necessary to make a statistical analysis using data from [Conley et al. (2011)][XConley2011] and [Sullivan et al. (2011)][XSullivan2011].

Is also supports [Betoule et al. (2014)][XBetoule2014].

Ancestors

Constructors

nc_snia_dist_cov_new

Creates a new NcSNIADistCov object for Type Ia supernovae distance modulus with covariance matrix.

nc_snia_dist_cov_new_by_id

Creates a new SNIa model using the default values for the sample defined by snia_id.

Functions

nc_snia_dist_cov_clear

If dcov is not NULL, decreases the reference count of dcov and sets dcov to NULL.

Instance methods

nc_snia_dist_cov_alpha_beta

Returns the values of $\alpha$ and $\beta$.

nc_snia_dist_cov_calc

Computes the covariance matrix for the SN Ia distance estimates. If the covariance matrix is already computed and the parameters are the same, the function returns FALSE.

nc_snia_dist_cov_extra_var

Computes the total variance of the i-th distance, not related to the magnitude, width or colour errors.

nc_snia_dist_cov_free

Decreases the reference count of dcov. If the reference count reaches 0, the object is freed.

nc_snia_dist_cov_mag

Computes the apparent magnitude from model, width and colour.

nc_snia_dist_cov_mag_to_width_colour

Computes effective observed vector obs, the first snia_cov->mu_len parameters are set to the width colour combination using the values of the distance modulus from the model cosmo and the SNIa model dcov, i.e., $-\alpha{}w_i+\beta{}c_i = m_{\mathrm{B},i} - \mu_{\mathrm{th},i}-\alpha-\mathcal{M}_i$. The next 2 * snia_cov->mu_len are the observed widths and then the observed colours.
