Descriptions
We measure the B-band luminosity function, stellar mass function and projected 2PCF with the zCOSMOS bright sample. Here are our results.
luminosity_function_B.hdf5 : B-band luminosity function measured from the zCOSMOS bright sample.
In the hdf5 file, the group "LF_z1_z2" store the LF in the redshift range [z1, z2]. The members in the group are:
- M_B : absolute magnitude of B-band
- LF : value of luminosity function
- LF_err : error of luminosity function
stellar_mass_function.hdf5 : Stellar mass function measured from the zCOSMOS bright sample.
In the hdf5 file, the group "GSMF_z1_z2" store the GSMF in the redshift range [z1, z2]. The members in the group are:
- Stellar_Mass : $\log_{10}(M_*/M_\odot)$
- GSMF : value of stellar mass function
- GSMF_err : error of stellar mass function
projected_2pcf.hdf5 : Projected 2PCF measured from the zCOSMOS bright sample.
In the hdf5 file, the group "wp_z1_z2" store the projected 2PCF in the redshift range [z1, z2]. The subgroups "mass_m1_m2" store the wp in the stellar mass bins [m1, m2], where the unit of m1 and m2 is $\log_{10}(M_*/M_\odot)$. The members in the subgroup are:
- r_p : projected distance, unit is $h^{-1}{\rm Mpc}$
- wp : value of projected 2PCF
- wp_err : error of projected 2PCF
F_theta.hdf5 : The function $f(\theta)=(1+w_p)/(1+w_s)$ to correct the fiber collision effect.
In the hdf5 file, the group "F_theta_z1_z2" store the $f(\theta)$ in the redshift range [z1, z2]. The subgroups "mass_m1_m2" store the $f(\theta)$ in the stellar mass bins [m1, m2], where the unit of m1 and m2 is $\log_{10}(M_*/M_\odot)$. The members in the subgroup are:
- theta : angular distance, unit is degree.
- F_theta : value of $f(\theta)$.
