(*): This camera is a multi-detector instrument; it is recommended to split multi-extension FITS frames from this instrument into individual single-extension FITS images and to run the pipeline on these individual FITS images.
(**): SOAR Goodman image header have a number of non-standard keywords
that force astropy to crash; in order to use PP, please remove header
keywords PARAM0, PARAM61, PARAM62, and PARAM63 prior
to running PP, e.g., using the delhead command provided by
WCSTools.
(***): wcs provided with telescope data is usually excellent; in this case
I suggest skipping registration and to use pp_run with the
-keep_wcs option.
It is recommended to stitch images from cameras with multiple amplifiers together using the correct orientations. Furthermore, it is recommended to flatten FITS files with multiple headers by simply combining the individual headers under a single extension.
Supported Reference Catalogs¶
PP is currently able to use the following catalogs for astrometric and photometric calibration:
| Catalog Name | Catalog Type | Registration? | Filter Bands | Comments |
|---|---|---|---|---|
| Gaia DR1 (Gaia) | astrometric | yes | G | all-sky catalog, excellent astrometry, G < 20 mag |
| Gaia/TGAS (TGAS) | astrometric | yes | G | all-sky catalog, excellent astrometry, G < 12 mag |
| USNO-B1.0 | astrometric | yes | R2 | good astrometry, V < 21 mag |
| 2MASS (2MASS) | astrometric/photometric | yes | J, H, Ks, K* (Vega) | all-sky NIR catalog, good astrometry |
| URAT-1 (URAT-1) | astrometric/photometric | yes (SCAMP >= trunk.r345) | g, r, i (SDSS AB); B, V, R*, I* (Vega) | good coverage over the Northern hemisphere, photometry from APASS (see below) |
| Sloan Digital Sky Survey Release 9 (SDSS-R9) | astrometric/photometric | yes | u, g, r, i, z (SDSS AB); U*, B*, V*, R*, I* (Vega) | excellent photometry, Northern hemisphere, patchy coverage |
| AAVSO Photometric All Sky Survey Release 9 (APASS9) | photometric | no | g, r, i (SDSS AB); B, V, R*, I* (Vega) | good coverage, good photometry for stars with V<17 |
| Pan-STARRS DR1 (PANSTARRS) | photometric | no | g, r, i, z, y (SDSS AB); B*, V*, R*, I* (Vega) | good coverage, good photometry for stars with V<20; currently, only cone searches with radius < 0.5 deg supported |
| SkyMapper DR1 (SkyMapper) | photometric | no | u, v, g, r, i, z (SDSS AB) | good coverage in the Southern hemisphere |
The catalog name in brackets is the identifier used by PP; e.g., if
you want to use URAT-1 for the registration of your images, use option
-cat URAT-1 with the pp_register command. The “Registration?”
column identifies if this catalog is supported by SCAMP in order to
use it for image registration. All filter bands marked with an
asterisk (*) are obtained through transformations from other bands;
the respective photometric system is shown in brackets.
Supported Catalog Transformations¶
PP supports the following catalog transformations:
- ugriz -> BVRI: Chonis & Gaskell 2008
- JHKs (2MASS) -> JHK (UKIRT): Hodgkin et al. 2009
- Pan-STARRS grizy -> SDSS griz + BVRI: Tonry et al. 2012
Independent checks indicate that these transformations are reliable and accurate. More quantitative results coming soon…
