- craftutils.wrap.galfit.feedme_sky_model(background_center: float = <Quantity 1.392 adu>, fit_background_center: bool = True, gradient_x: float = <Quantity 0. adu / pix>, fit_gradient_x: bool = True, gradient_y: float = <Quantity 0. adu / pix>, fit_gradient_y: bool = True, skip_in_output: bool = False, **kwargs)
Generate input file lines in the GALFIT feedme format, for sky model. Parameters provided in valid astropy units will be converted to the units used by GALFIT. :param background_center: Background level at centre of fitting region.
Corresponds to item 1) in the GALFIT feedme definition.
- Parameters¶
- fit_background_center
If True, GALFIT will fit for background_center; if False, it will remain fixed.
- gradient_x
dsky/dx in ADU / pixel Corresponds to item 2) in the GALFIT feedme definition.
- fit_gradient_x
If True, GALFIT will fit for gradient_x; if False, it will remain fixed.
- gradient_y
dsky/dy in ADU / pixel Corresponds to item 3) in the GALFIT feedme definition.
- fit_gradient_y
If True, GALFIT will fit for gradient_y; if False, it will remain fixed.
- skip_in_output
Skip in output image block? Corresponds to item Z) in the GALFIT feedme definition.
- pix_scale
pixel scale for conversion from angular sizes (eg arcsec) to pixels.
- Returns¶
List of strings corresponding to lines in a .feedme input file, suitable for use with open().writelines().
