lightkurve.KeplerTargetPixelFile.from_fits_images#
- static KeplerTargetPixelFile.from_fits_images(images_flux, position, images_raw_cnts=None, images_flux_err=None, images_flux_bkg=None, images_flux_bkg_err=None, images_cosmic_rays=None, size=(11, 11), extension=1, target_id='unnamed-target', hdu0_keywords=None, **kwargs)#
Creates a new Target Pixel File from a set of images.
This method is intended to make it easy to cut out targets from Kepler/K2 “superstamp” regions or TESS FFI images.
- Parameters
- images_fluxlist of str, or list of fits.ImageHDU objects
Sorted list of FITS filename paths or ImageHDU objects to get the flux data from.
- positionastropy.SkyCoord
Position around which to cut out pixels.
- images_raw_cntslist of str, or list of fits.ImageHDU objects
Sorted list of FITS filename paths or ImageHDU objects to get the raw counts data from.
- images_flux_errlist of str, or list of fits.ImageHDU objects
Sorted list of FITS filename paths or ImageHDU objects to get the flux error data from.
- images_flux_bkglist of str, or list of fits.ImageHDU objects
Sorted list of FITS filename paths or ImageHDU objects to get the background data from.
- images_flux_bkg_errlist of str, or list of fits.ImageHDU objects
Sorted list of FITS filename paths or ImageHDU objects to get the background error data from.
- images_cosmic_rayslist of str, or list of fits.ImageHDU objects
Sorted list of FITS filename paths or ImageHDU objects to get the cosmic rays data from.
- size(int, int)
Dimensions (cols, rows) to cut out around
position.- extensionint or str
If
imagesis a list of filenames, provide the extension number or name to use. This should be the same for all flux inputs provided. Default: 1.- target_idint or str
Unique identifier of the target to be recorded in the TPF.
- hdu0_keywordsdict
Additional keywords to add to the first header file.
- **kwargsdict
Extra arguments to be passed to the
TargetPixelFileconstructor.
- Returns
- tpfTargetPixelFile
A new Target Pixel File assembled from the images.
