[AstroPy] how to determine whether a point was observed by hst ever?

[gonghang.naoc]

hi,
Thank you. I tried one position with a same ra&dec&radius and it seems
there is a big difference between that url output and the stsci output.
The fits names are different. So I use observation time,but the time is not
the same at all either.
