HiPS, added your server/Hips

[Martinus Meiborg]

Hi!

I am creating a HiSP (Sky Survey) which I would like to view in Stellarium.

I followed chapter 10.2 in the guide, and edited the config file: (1) add URL,  and (2) increased 'surveys/size by one:

[hips]

show                                   = true
surveys/1/url                          = http://cade.irap.omp.eu/documents/Ancillary/4Aladin/LAB_NH
surveys/2/url                          = http://[url to my Hips]
surveys/size                           = 1

The Hips wil not load. In the config sources/size will set back to '1'. (It would be great if that could work with an external URL...)

Also experimented with the instructions of chapter 10.4, just to be sure, but expected it wouldn't work. Added to the config file:

[astro]
toast_survey_directory = [path to my local directory]

toast_survey_host=/
toast_survey_levels =10

Load time of the surveys in the Sky and Viewing Window (F4) >> Surveys-button increases.... but nothing extra to select... (likely only works with local versions that are in the online list?)

Anyhow. Is there a way to load your own Hisp in Stellarium?

Cheers,

Martinus Meiborg

Why? I see the survey (see an attachment), but I removed line surveys/2/url

Sure, we have documented this so you can load your own self-hosted one. From the User Guide you see that a file "hipslist" is expected to exist. Did you provide this?

The section 10.4 describes the older way of getting DSS on screen, optionally offline on a field laptop.

Hi Georg,

As I understand, 'hispslist' describes a catalog of HiPS including the URLs where to find them. The [hips] entry in config.ini however shows the HiPS-serveys that were open when you quit, so that Stellarium opens them again when you start it. The [hips] entry points to surveys,  not  hipslists, correct me if I am wrong (the hipslists that Stellarium loads are not in config.ini). Nevertheless, to be sure, I have put a basic hipslist in the directory of my survey.

Looking at the [hips] entry in config.ini:

When I open config.ini it looks like this:

[hips]
show                                   = true
surveys/1/url                          = http://cade.irap.omp.eu/documents/Ancillary/4Aladin/LAB_NH/
surveys/size                           = 1

This is correct, that was the open survey when I quitted Stellarium.
@Alexander: you have sent an image of this survey. It is not mine, surveys/2/url was mine.

Manually I added my HiPS-directory (with an example URL, as it is not ready to go public):

[hips]
show                                   = true
surveys/1/url                          = http://cade.irap.omp.eu/documents/Ancillary/4Aladin/LAB_NH/
surveys/2/url                          = https://mydomain.com/HIPS/LABH_RGB/
surveys/size                           = 2

When I open Stellarium, neither survey appears. When I quit, the [hips]-entry is empty:

[hips]
show                                   = true

When I open Stellarium again and select two surveys and quit, the config.ini shows:

[hips]
show                                   = true
surveys/1/url                          = https://alasky.cds.unistra.fr/MellingerRGB
surveys/2/url                          = http://cade.irap.omp.eu/documents/Ancillary/4Aladin/LAB_NH
surveys/size                           = 2

Conclusion: apparently Stellarium does not accept a 'strange' URL. Both URL's given in the first example. (http://cade.irap.omp.eu/documents/Ancillary/4Aladin/LAB_NH, and https://mydomain.com/HIPS/LABH_RGB/) open fine in Aladin. 

For now I am not sure how to run my own HiPS for testing. Question remains: what to do?

Cheers,
Martinus

According to the User Guide, you must configure sources (URL where hipslist can be found), not surveys (the actual hips directory name). I just tried my own localhost server, it still works.

[Martinus Meiborg]

And then you see your HiPS in de survey list in the Sky and viewing options window? Or how do you load them if not directly visible?

In any case , thanks for your patience, I will try again…

Yes, all hips announced in all hipslist files of all sources are available in the selection list. You must activate the checkbox to display, and only one can be displayed at a time.
Make sure to check in your own webbrowser and call up your own hipslist for a test.

[Martinus Meiborg]

I tried he following:

The manual section 10.2 shows this in the show this example, note it mentions 'sources' and 'hipslist':

[hips]
sources/1/url = http://alasky.u-strasbg.fr/MocServer/query?*/P/*&get=record 

sources/2/url = https://data.stellarium.org/surveys/hipslist
sources/3/url = http://localhost/Stellarium/hips/hipslist
sources/size = 3

The hips-section in my config.ini doesn't list sources, it lists open surveys:

[hips]
show                                   = true
surveys/1/url                          = https://alasky.cds.unistra.fr/2MASS/K
surveys/2/url                          = https://alasky.cds.unistra.fr/2MASS6X/2MASS6X_color
surveys/3/url                          = http://cade.irap.omp.eu/documents/Ancillary/4Aladin/LAB_NH
surveys/size                           = 3

There is no 'sources' section in my config.ini.

I have tried two things:

1. clear all surveys and add 'sources' + one my hipslist on my localhost server, so that it complies to the top format. It doesn't work.

2. I added the url to the survey on my localhost server as open survey... The survey doesn't show, and after quiting Stellarium 'size' is set back to '1', as explained earlier in this thread.

In short, it doesn't seem to be possible to load local surveys. If it is possible, the instructions in the manual are not complete.

Any clues?

Then add it! The first two shown are the default entries. Only when you deviate by having more you need these entries.
