class Mag

abstract class to handle everything related to the computation of expected magnitudes

Subclassed by GalMag, QSOMag, StarMag

Public Functions

Mag(keymap &key_analysed)

Build a Mag instance from the keywords common to GAL/QSO/STAR runs (config file, object type, cosmology, IGM opacities)

Parameters:

key_analysed – map of keyword/value pairs parsed from the configuration file and command line

inline Mag()
virtual ~Mag()
void read_ext()

read the extinction laws into attribute extAll (vector of vectors of type ext)

void read_B12()

Read the long wavelength Bethermin+2012 templates to add the dust emission to the BC03 templates

void def_zgrid()

define the vector of redshifts, and associate to it vectors of age and distance modulus, based on the lcdm attribute

inline void set_zgrid(double dz, double zmin, double zmax)

helper function to set the grid of redshift

Parameters:

  • dz – : step in z in the grid

  • zmin – : minimum z

  • zmax – : maximum z

void write_doc()

Write in file sdocOut the documentation for the GALAXY/QSO/STAR case.

virtual void print_info()

print general information onscreen, valid for GAL/QSO/STAR objects

void open_files()

open all the input and output streams needed for the computations

void close_files()

close all opened files

virtual void read_SED() = 0

read SED files, apply extinction corrections, and store into a vector of instances of class SED
