Seadas 8.1 modis_atteph didn't return all records but T2022.2 did

[yuyuanxie]

8.1 (T2021.12) is the version I'm currently working with. But in a rare chance (8/3432), its modis_atteph didn't return all records, but T2022.2 could for those cases. However, I don't trust T2022.2 for now, I posted another thread about more errors in T2022.2 modis_atteph and getanc in different cases.

### in 8.1, only 2 att records returned, then modis_GEO couldn't work ###
