    Data Photometry
AI Thread Summary
To obtain photometry from SDSS data, users can utilize the SDSS Explore tool by entering the specific ObjID of the objects. If the ObjID is unknown, users can find it using the object's Right Ascension (RA) and Declination (Dec) coordinates. The discussion highlights that the Explore tool provides both spectra and photometry once the ObjID is accessed. A link to the relevant SDSS tutorial for spectra is also shared, indicating a similar approach may be possible for photometry. Overall, the process is straightforward for those with the necessary identifiers.

Does anyone have any idea how to get the photometry of SDSS data?

From http://cas.sdss.org/dr6/en/" .

Is there anything in particular that you are looking for?

Actually I would like to find the spectra and photometry for a set of objects,
I can find the spectra here:
http://www.sdss.org/dr6/tutorials/colorconstraints.html
I am wondering if I can find the photometry in a similar way?

Do you have the ObjID of the objects?

If so, then it's a piece of cake! Just use http://cas.sdss.org/astro/en/tools/explore/obj.asp" .

For example, ObjID is 588298663036649507, http://cas.sdss.org/astro/en/tools/explore/obj.asp?id=588298663036649507"'s what the Explore tool gives you, complete with spectra AND photometry! :smile:

If you don't know the ObjID, but do know the RA and Dec, then it's just one more step ...

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
