根据错误信息，看起来在`bs_data`数据框中没有名为'覆盖场景No'的列。请确保列名的拼写和大小写与数据框中的实际列名完全匹配。

如果你想要查看`bs_data`数据框的列名，可以使用`columns`属性：

print(bs_data.columns)

另外，还要确保索引为0的行存在。如果你的数据框中没有任何行，或者索引为0的行不存在，那么`bs_data['覆盖场景No'][0]`会引发`KeyError`错误。你可以通过检查数据框的形状来确认是否存在至少一行：

print(bs_data.shape[0] > 0)

确保数据框不为空，并且列名正确拼写和大小写匹配后，再次尝试访问`bs_data['覆盖场景No'][0]`应该就不会报错了。

根据错误信息，看起来在使用`w_data[w_data['波束场景No'] == cross_data['波束场景No'][0]]`时出现了`KeyError: '波束场景No'`错误。这个错误通常表示在`w_data` DataFrame中不存在名为'波束场景No'的列。

要决这个问题，你可以先检查一下`w_data` DataFrame的列是否与你使用的列名完全配。请确保列名的拼写和大小写与数据框中的实际列名一致。

你可以使用`columns`属性来查看`w_data` DataFrame的列名：

print(w_data.columns)

确保列名正确拼写和大小写匹配后，再次尝试运行`w_data[w_data['波束场景No'] == cross_data['波束场景No'][0]]`应该就不会报错了。
