beamingfactor 0.2.0

Program to compute beaming factor.

Beaming Facor Library

A pre-computed beaming factor library is presented in directory BeamingFactor_Lib.
(Beaming factors fro SDSS(ugriz) systems under PHOENIX will soon uploaded in several days.)

BeamingFactor

Installation:

  We present python based program BeamingFactor for users who want to compute factors themselves.
  (will soon be available in several days)

 pip install beamingfactor  

Usage:

Examples:

import beamingfactor as bf
bf.factor(specfile='/path/to/file/file_name',spectype='PHOENIX',K=100)  

Supported Parameters

Supported Input Spectra Files:

Users can specific synthetic spectra (files direct download from PHOENIX[^1](Must use high resolution file), Atlas9, or TMAP), for example:

bf.factor(specfile='/path/to/file/file_name',spectype='ATLAS9')

Users can specific their own flux calibrated spectra as follows:

bf.factor(specfile='/path/to/file/file_name',spectype='USER')  

• Files should be an ascii format csv file.
• First column should be wavelength in Angstorm and second column being flux, seperated by comma.
• First line can be comments or colnames begin with '#'.

For example:

#Wave,Flux  
200,2.0  
3000,2.1  

Supported Input Filter Passband:

Supported spectype included: ATLAS9, PHOENIX, TMAP, and USER.
Filter name should be given with band='Filter_Name'.
Support Filter_Name: u,g,r,i,z,TESS,G,Gbp,Grp,U,B,V,R,I,kepler,NUV_CSST,u_c,g_c,r_c,i_c,z_c,y_c

u,g,r,i,z are from SDSS;

NUV_CSST,u_c,g_c,r_c,i_c,z_c,y_c are from CSST

TESS for TESS

kepler for Kepler

For Example:

bf.factor(specfile='/path/to/file/file_name',spectype='ATLAS9',K=100) 

[^1]: Must use high resolution (R=500,000) file.
