pixel_to_world(40, 40) #将(40,40)这个像素的坐标转换为天球坐标。 print(sky) f.close() pixel_to_world将输入的像素坐标参数转换为了Header中对应的天球坐标。查看Header发现,此处转换为了赤经(ra)和赤纬(dec)坐标,单位是deg(degree): <SkyCoord (ICRS): (ra, dec) in deg (5.52884629, -72.05203)>...
WCSAxes is a package that makes it easy to plot images with world coordinate system (WCS) information (which translates pixel to 'world' coordinates and back) using Matplotlib. Originally intended for use with Astronomical data, WCSAxes can be used with any data provided that an appropriate WCS...

Write WCS to a new file (default is read-only) -x X and Y coordinates of reference pixel (default is image center) -y multiply image dimensions by this for search (default is 1) -z Use AIPS classic projections instead of WCSLIB; use CD matrix or CDELT instead of polynomial solution....
Defines how to interpolate pixel values. By default, this will be set to the service's resampling method, if it has one. If the service does not have a default resampling method, the bilinear resampling will be used in most cases, and nearest interpolation type will be used for thematic ...
The FITS format supports World Coordinate System ("WCS") calibrations that relate column, row positions to standard coordinate systems or physical dimensions. The FITS WCS is supported by all Mira version 7 platforms. The FITS WCS standard evolved from a number of different calibration schemes ...

Note that you adjust each source pixel value relative to the neutral axis at that lightness value. This assures that source device neutrals will fall on the neutral axis of the appearance model. You also shift all other colors at that lightness by the same amount, so that there are no disc...
