THELI core components
The THELI GUI is bound to a fixed version of the THELI pipeline core to ensure compatibility. You must use the pipeline core version linked above.

External package: Astrometry and photometry
We highly recommend you download the latest Scamp (thanks Emmanuel Bertin!) version from the repository, and compile it. If you don’t suceed, you may use Scamp v1.4.6, which is the last fully statically compiled version and we provide here for convenience.
SDSS ugriz photometric reference catalog
We provide a subset of the SDSS stripe 82 photometric calibration catalog (Smith 2007). The original published version of this catalog contains about 1000000 stars. We keep only sources with individual errors less than 0.05 mag in all filters, and remove very faint sources in gri filters which could lead to a systematic bias of 0.02 mag in the ZP. About 340000 photometric reference sources remain.
Stripe 82 is located between 20:30:00 < RA < 04:00:00, and -1.27 < DEC < 1.27. By downloading the tarball below, you will obtain two versions of the catalog, one for the SDSS native ugriz system, and one for the USNO-1m u’g’r’i’z’ system.
In order to use these catalogs, you have to unpack the tarball in gui/photstdcats/.
