- Retrieve spectra using Simple Spectral Access protocol
- UCDs: working with heterogeneous tables
- Creating a VO Table from a CSV file
- Science User Case - Inspecting a Candidate List
- 1. Import the Python modules we’ll be using.
- 2. Search NED for objects in this paper.
- 3. Filter the NED results.
- 4. Search the NAVO Registry for image resources.
- 5. Search the NAVO Registry for image resources that will allow you to search for AllWISE images.
- 6. Choose the AllWISE image service that you are interested in.
- 7. Choose one of the galaxies in the NED list.
- 8. Search for a list of AllWISE images that cover this galaxy.
- 9. Use the .to_table() method to view the results as an Astropy table.
- 10. From the result in 8., select the first record for an image taken in WISE band W1 (3.6 micron)
- 11. Visualize this AllWISE image.
- 12. Plot a cutout of the AllWISE image, centered on your position.
- 13. Try visualizing a cutout of a GALEX image that covers your position.
- 14. Try visualizing a cutout of an SDSS image that covers your position.
- 15. Try looping over all positions and plotting multiwavelength cutouts.
