Stellarium 버전 0.9.0에서 스타 카탈로그는 밝기를 변화의 스타가 포함된 9 파일을 분할하고 있습니다. 이러한 파일은 <설치의 directory>에 / 스타 / 기본값을 찾을 수 있습니다 /. 오직 4 개의 작은 이러한 파일의 Stellarium와 메인 패키지에 크기가 관리 유지왔다.
이러한 모든 항성의 99 % 정도가 USNO하여 방랑자 카탈로그 (해군 관측소 합병 천체 데이터 집합 버전 1)에서 온. 나머지는 (밝은 것들) Tycho2과 Hipparcos에서. 제발, 어느 아래 노매드에서 발생하는 파일의 데이터를 재배 포할 수있는 조건에 대한 stellarium의 README 파일을 참조하십시오.
여기에 사용할 수있는 모든 카탈로그의 목록입니다. RAM이 필요한 열을 시작할 때 일반 카탈로그로드의 경우에, 적용 및 견적입니다. (MNG 512 미터 숫양 7 파일을 로드할 수 있지만 막. YMMV) 관리됩니다. mmap로드 시스템 메모리에 대한 제한을 더 이상, 다음 섹션을 참조하지 않습니다.

How to add catalogs
Stellarium 0.10.1 will have an automatic download feature built into the program. To use it, hit [F2] or click on the Configuration button on the left panel. Click on the Tools tab. At the bottom of the dialog, a box called "Star catalog updates" should say "Checking for new star catalogs". After a moment, a button labeled "Get star catalog x of y" should appear. Click on this button to download the first catalog. Once the download completes, the button will appear again if there are more catalogs available. Keep clicking on this button to download all extra catalogs.
Note that you can still manually edit stars.ini, as in previous versions.
Note: starting stellarium with:
won't do (the program won't be able to write the downloaded files to their directories).
$ sudo stellarium
should be used instead of the former.
0.9.0 - 0.10.0
NOTE: when downloading from this page, do not right-click and save as - left click. These are not direct download links - they are links to the list of download mirrors. Left click on them, and wait for your download to start.
For using stars_7_2v0_0.cat I recommend 1GB of RAM, and for stars_8_2v0_0.cat at lease 1.5GB. In version 0.9.0 the catalogs are just loaded into RAM, and if you do not have enough of it, swapping will start. Add up the star catalog sizes, compare with your amount of RAM, and your common sense will tell you how many files you can load. Yours, Johannes
Since version 0.9.1 you can instruct your computer to load all the stars into main memory not at startup, but to load groups of stars when they are displayed for the first time. This is done using the operating systems mmap function, hence the name "mmap loading". Using this technique you can use all of the star catalogs even if you have very little RAM. Also the initial startup time is greatly decreased. The drawback is that your computer loads the stars during normal program operation, when they are used for the first time. Therefore the scrolling and zooming will not be so smooth as when you load all catalogs at startup in advance.
In config.ini, under the [stars] heading, set the key "max_memory" to the maximum amount of memory, in megabytes, to use to load star catalogs directly (the old way). Any catalogs that would push the total memory used over that value will be memory mapped. If unset, the value defaults to 128.
0.9.1 and 0.10.0
For each catalog file that you want to use, you can decide if you want to load it at startup or using mmap by prefixing the catalog name with "mmap:" in stars.ini:
[stars] cat_file_name_00 = stars_0_0v0_1.cat cat_file_name_01 = stars_1_0v0_1.cat cat_file_name_02 = stars_2_0v0_1.cat cat_file_name_03 = stars_3_1v0_0.cat cat_file_name_04 = stars_4_1v0_0.cat #you can use mmap loading, if you do not want to load all stars #immediately into RAM: cat_file_name_05 = mmap:stars_5_2v0_0.cat cat_file_name_06 = mmap:stars_6_2v0_0.cat cat_file_name_07 = mmap:stars_7_2v0_0.cat cat_file_name_08 = mmap:stars_8_2v0_0.cat cat_hip_sp_file_name = stars_hip_sp_0v0_0.cat cat_hip_cids_file_name = stars_hip_cids_0v0_0.cat
In this example mmap loading is configured for stars_5,...,stars_8 only.
Caveat: when using mmap loading, you must use catalog files that match your computers hardware architecture and the compiler used for building stellarium. The ordinary .cat files can be used with little endian computers and gcc: this applies to all PC (i368 and x86_64 architectures) and the newer Intel macs. Nigel Kerr has made a program for converting .cat files into .bcat files, which can be used with big endian computers and gcc (primarily for the older macs with PPC architecture). All others must use my program ConvertCatToNative.C (in the util directory) for converting .cat (or .bcat) files into a native format appropriate for their architecture and compiler.
Prior to version 0.9.1 the files stars_3_1v0_0.cat and stars_5_2v0_0.cat were falsely called stars_3_0v0_0.cat and stars_5_1v0_0.cat. Now this misnaming is fixed. The contents of the files is unchanged, just the names have been fixed in order to reflect the contents, which is stars of type 1 and of type 2, respectively. All you have to do is make sure your file stars.ini lists the names of your star catalog files, no matter whether you use the new names or the old ones.
