对应的儒略日为: 2460360.5 在这个例子中,我们用Time类创建了一个时间对象,并通过.jd属性轻松获取到对应的儒略日。 小贴士:Astropy的Time模块不仅支持ISO格式,还支持多种其他格式,比如MJD(修正儒略日)、unix时间戳等。非常适合用于天文观测数据的时间戳处理。 5. Astropy的坐标转换:轻松搞定坐标系 天文学中,天体...
Astropy的time模块可以处理各种时间格式,包括UTC、JD、MJD等。 以下示例展示如何将UTC时间转换为JD时间。 fromastropy.timeimportTime # 创建一个UTC时间对象 utc_time=Time('2023-10-01 00:00:00',scale='utc') # 转换为JD时间 jd_time=utc_time.jd print(f"JD时间:{jd_time:.5f}") 单位和量 Astrop...
One can make a scalar masked Time, but the value is lost (set to J2000) In [3]: Time(Masked(50000, mask=True), format="mjd") Out[3]: <Time object: scale='utc' format='mjd' value= ———> In [4]: Time(Masked(50000, mask=True), format="mjd").unmasked Out[4]: <Time ...
Description If a FITS header has a spectral axis and OBSGEO-* keywords but no MJD-DATE, then _get_components_and_classes crashes because it tries to construct a Time from a NaN MJD. I'm not aware of any requirement in the FITS specificat...

I took a look at what wcslib does and how it's wrapped. I think wcslib actually has a different bug, in that when it computes MJD-OBS from DATE-OBS it doesn't treat that as a change and hence doesn't produce a message. It looks like wcsfixi returns, for each fixer, both a me...
