Batch Classification

Upload a CSV file containing multiple objects, with 11 features corresponding to SDSS DR18

Click or drag CSV file here Max size: 5MB

Target Columns: ra, dec, redshift, psfMag_r, u, g, r, i, z
Exact Headers: The CSV file must contain precisely these lowercase headers in the correct arrangement. All fields must be numeric.
⚠️ Action Failure: Failing to format the columns correctly, including non-numeric artifacts, or submitting extraneous indices will immediately trigger a payload rejection and throw server-side errors, aborting the process.
