Propagation of physical quantities in the calculation of luminosities of galaxies
Created: 2011-11-30 16:31:30
Last updated: 2013-04-22 16:07:16
This workflow takes as input a file for each of this properties: J2000 Coordinates, velocity, galactic extinction, log of axis ratio, and the Total B-magnitude. With this properties it calculates the distance of the galaxy and, in other hand, the total apparent corrected B-magnitude.
It takes account if the velocity of the galaxy is lower than a threshold (1000km/s), it can not be possible to calculate the distance so, in those cases the distance will be "NaN".
At the end, it calculates the total luminosity using the velocity and the total apparent corrected B-magnitude.
More information in the nested workflows.

Name |
Description |
type_morpho |
Text file with three columns: the name of the galaxy, the morphological type of the galaxy, the error value.
If there is not error value, it will be NaN
|
fileCoordsJ2000 |
Text file with three columns: the name of the galaxy and the J2000 coordinates of the galaxy in sexagesimal degrees with no separation chars.
|
velocityFile |
Text file with three columns: the name of the galaxy, the velocity of the galaxy in km/s and the error value.
If there is not error value, it will be NaN
|
agFile |
Text file with three columns: the name of the galaxy, the correction for the dust extinction produced by our own galaxy, and the error value. If there is not error value, it will be NaN
|
btFile |
Text file with three columns: the name of the galaxy, the total B-Magnitud of the galaxy and the error value.
If there is not error value, it will be NaN
|
logr25File |
Text file with three columns: the name of the galaxy, the value for the axis ratio of the isophote 25 mag/arcsec2 in the B-band (logr25) of the galaxy and the error value. If there is not error value, it will be NaN
