I found the following Table online in this document (page 11): www.ivoa.net/documents/HiPS/20170406/PR-HIPS-1.0-20170406.pdf
First item is the Norder, second is the number of files (or tiles), third item is the angular size of each tile, fourth item is the angular size of each pixel in each tile.
So for example, if you are wishing to use the HiPS for framing, this tells you that Norder5 provides you with 12.88 arc seconds per pixel, which each tile being 1.832 degrees across.
Norder7 has each tile 27.48 arc minutes across, with a pixel size of 3.221 arc seconds.

FYI, Norder8 would be around 78GB in size, with a pixel size of 1.61 arc seconds (it appears to halve as you raise the HiPS order by 1)

0 12 58.63° 6.871'
1 48 29.32° 3.435'
2 192 14.66° 1.718'
3 768 7.329° 51.53”
4 3072 3.665° 25.77”
5 12288 1.832° 12.88”
6 49152 54.97' 6.442”
7 196608 27.48' 3.221”

Having been out of torrents for a long time. What is the recommended client?

I dont want malware :) Windows preferred.

Also if i run Kstars on windows where do i put the files? everything i have seen is linux paths.

Thanks!

Would it fry my Pi if I copy all the files from Norder 1 to 7 on its SSD? :D

Copying maybe not (if the SSD is large enough).
Zooming in and out in KStars starmap, probably yes :evil:

Should be ok if you have the space. But you probably don't need 6-7. Level 5 is pretty detailed.

If you use the DSS Color quite a bit, then I find having them local makes for a smoother scroll / pan / zoom experience.

Okay, the download & extraction is now complete. I'll first copy Norder 1 to 5 and try how the Pi/ KStars performs. If all goes well, will try the 6 & 7 as well.

Can you give quick instructions on how you downloaded them? I used that original dropbox link and i would like to learn the proper way.

Thanks!

Sure, Chad

I actually used the four torrent links provided one after the other on Giles' blog post on the topic here:

coochey.net/?p=699

You need a torrent client to download, of course. The first one had Norder 1 to 4, and the other three had 5, 6, and 7 thereafter.

I ended my torrent seeding, let me know if you want it re-enabled (and seed some more).

I still seed the 1-4 level. But only when my computer is left on.
