I am working on "Sloan digital sky survey DR14" dataset and trying to categorized attributes into Nominal, Ordinal, Interval and Ratio data types. I have divided as following:
Nominal = "objid" "rerun" "run" "native" "field" "specobjid" "fiberid"
Ordinal = "camcol"
Ratio = "dia" "ra" "dec" "u" "g" "r" "i" "z" "m_unt" "flux" "plate"
Interval = "redshift" "mjd"
Is it correct?
Edit: Link to that dataset
Hello, folks. I am starting to use SDSS to download information and images of certain sectors of the sky. The problem is that I am not very used to SQL and I am just learning how to play with it. I would like to make a query that allows me to download FITS files ONLY from the body of different galaxies (in principle, 100 of them). It's possible?
I have been looking through their website but I thought someone here might know off hand.
Is the data regarding the speed of galaxy recession adjusted for earth's orbit and rotation?
TIA
This is probably the biggest single data dump about the state of cosmology since Planck's 2018 papers, the top of which has amassed >3k citations and their previous releases in '15 and '13 are up to >8k and >7k citations respectively. Here are the papers (let me know if I've missed any):

The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: measurement of the BAO and growth rate of structure of the luminous red galaxy sample from the anisotropic power spectrum between redshifts 0.6 and 1.0 (yes these two have the same title, but they seem to be different papers by different working groups)

Recent space probe data readings for the so called cosmic microwave background and sky surveys by the Sloan Earth-based, digital telescope mapping the visible stars from the Earth has revealed that our own Milky Way is at the axis or center of the known universe as we know it.Β This discovery and affirmation of galaxy mapping over almost 20 years may revise modern science's view that the Earth is not just a random planetary system, but in fact may hold something divine being in the center of the heavens.Β The Cosmic Microwave Background is said to be the afterglow of the Big Bang
NASA's Planck probe was able to fully map an image of the known universe, the arrow at the bottom left of the digitally enhanced galaxy map above points out that the Earth is at the center of everything and that all galaxies seem to be a meticuluously aligned, geometric web around Earth and the Milky Way as the center of the known universe.
Scientists have found the same CMB line of the visible cosmos from the sky, space probe and ground digital telescope data gathering projects have created a very interesting map of the known universe: galaxies are aligned in concentric spheres around the Earth and the Milky Way and that the cosmic microwave background converges on the Earth along its equator and on its axis making the Earth the center of the known universe.
The so called axis where all other galaxies seemingly align with the earth was given the name: "the axis of evil" because it went against all previously accepted scientific and cosmological theories of Copernican cosmological model.Β The previously cult favorite, Carl Sagan Cosmos TV show espousing random chaos coming together to form intelligent life, now looks like it has lost all credibility as the data from the Planck probe and the SD Sky Survey are now reinforcing the truth that the universe came into being not by any Big Bang.Β There is also an observably large and systematic difference between the size of quasars and galaxies between the

Edit since some astro omers have suggedted there actuslly isnt enough data to comb through to support a coin perhaps this is better http://www.reddit.com/r/CryptoCurrency/comments/22c69a/another_coin_idea_financial_fraudcoin_algo_would/
So maybe my Financial FraudCoin combing through public trading data is a better choice. (it seems to have upset a few people since it is being rapidly downvoted)

It could be called "NEOCoin" for near earth object coin or asteroid coin or extinction coin or vigilence coin spacecoin or similiar.
You would just assign paprameters to be defined as a nonce. For example a pixel in an image that changed by so many arc seconds between two images . Even false alarms would be given nonce points becuase they would have found something worth looking at by humans.
Instead of cgminer it would be astrominer or something.
All the algorithms for detection and accessing the huge swaths of data coming from the automated telescopes already exist.
It would be interesting to replace script algo with those in a new version of cgminer.
Would produceo some greatuseful info that really needs lots of computer power.
Now that i think of it the algo could also detection brightness variations or color vsriations in stars to do planet sesrching or other object change detection as well.
Planet coin!
As long as you time stamp the data detection and have one or more official secured repositories of the blockchain (which gives up lack of central trust authority for defense against 51% attacks) you shouldnt have any issues. Or perhaps the slaon sky survey pic repository is defense enough sjnce each found object in a forged blockchain would still have to match the prevoius found objects and also fold in a nonce factor associated with previous finds in the chain just like any chsin.
It could be some science establishment that holds and verifies the block chain whch would of course also be the science results itself as well as any block tractions i the blockchain.
Each detection nonce could be referenced by the latest image number and pixel and the previous image number and pixel where the object was moved as the nonce. Example nonce might be like Pic#12345pixl60000by234pic#12344(maybe no other pixel needed?) Plus of course the prevoius nonce factor nonce to make a continous blockchain. You might get more block solving coins for a another detection of a previously found object however that might require too much orbital prediction r

From what I've read, the SDSS is mapping and demonstrating structure to galaxy clusters, superclusters, and the overall universe.
However, my question is about the accuracy of our positioning of these objects relative to each other and our vantage point in both space and time. If these galaxies are moving (for example, Milky Way and Andromeda and their inevitable merge), is it not true that the galaxies mapped at this moment likely aren't in the same position, or even exist in the same form? I don't imagine SDSS applies some sort of rudimentary estimation/guessing algorithm in terms of positioning based on their distance from our point in space.
In terms of people extrapolating certain things out of these universe maps, is it possible for the "Great Sloan Wall" to not even exist at all, except from our vantage point in both time and space (slightly similar to say Orion's Belt and the positioning of those stars only from our point in space)? Unless I'm missing something, it seems like they're overlooking this aspect when they describe these large structures in the universe.
