Please select one of the coordinate system you use for your data.
Equatorial coordinates (J2000)
Please select the redshift you want to make distance computation from
Total velocity in km/s.
Total velocity in unit of the speed of light.
Cosmology/flow model parameters (assuming curvature flatness):
Bulk flow components

The input text file must have three columns:
The first column is the longitude coordinate in the system indicated above (in degrees from 0 to 360)
The second column is the latitude coordinate in the same system (in degrees from -90 to 90)
The third and last is the redshift, with units and rest-frame as specified above.
Here is an example:
300 10 450 45 -20 2000
for two galaxies one in (l=300, b=10, cz=450 km/s) and another in (l=45, b=-20, cz=2000 km/s).
Text output format
The output text will be formatted with the same line ordering as the input.
