Lookup your distances
Please select one of the coordinate system you use for your data.

Please select the redshift you want to make distance computation from

Cosmology/flow model parameters (assuming curvature flatness):

Bulk flow components

Distance outputs:

Please select output style

Now you need to select a file to upload

Please provide a text file to be uploaded for processing

Input file
The input text file must have three columns:
  1. The first column is the longitude coordinate in the system indicated above (in degrees from 0 to 360)
  2. The second column is the latitude coordinate in the same system (in degrees from -90 to 90)
  3. 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.
