我试图通过Astropy裁剪到FITS图像中的某个区域
我有这些数据可以裁剪到某个区域
COLUMN1: ID [none] Source ID
COLUMN2: RA (core) [degs] Right ascension of the source core
COLUMN3: DEC (core) [degs] DEcination of the source core
COLUMN4: RA (centroid) [degs] Right ascension of the source centroid
COLUMN5: DEC (centroid) [degs] Declination of the source centroid
COLUMN6: FLUX [Jy] integrated flux density
COLUMN7: Core frac [none] integrated flux density of core/total
COLUMN8: BMAJ [arcsec] major axis dimension
COLUMN9: BMIN [arcsec] minor axis dimension
COLUMN10: PA [degs] PA (measured clockwise from the longitude-wise direction)
COLUMN11: SIZE [none] 1,2,3 for LAS, Gaussian, Exponential
COLUMN12: CLASS [none] 1,2,3 for SS-AGNs, FS-AGNs,SFGs
COLUMN13: SELECTION [none] 0,1 to record that the source has not/has been injected in the simulated map due to noise level
COLUMN14: x [none] pixel x coordinate of the centroid, starting from 0
COLUMN15: y [none] pixel y coordinate of the centroid,starting from 0
我不知道如何用RA,DEC裁剪区域。您能帮我解决这个问题吗？
谢谢。
