Possible VSX catalog duplicates

Technology VSX
1

Hello.
While using VSX, I noticed a possible duplicate variable star entry. ZTF19aaclksh and ZTF18abnbldg share identical coordinates. I verified their information: ZTF18abnbldg has coordinates 20 46 47.344 +17 13 05.69 (311.6972658 +17.2182467).

In addition, there are also the following similar duplicate entries of coordinates:

CzeV3617 = SERIV 169
SERIV 172 = CzeV3626
ZTF18abbogxd = ZTF18abacprn
KaiV115 = ASASSN-V J054436.36+405828.2

Best wishes,

Hi.
I recently wrote a Python script to check variable stars across the entire VSX. I once again discovered some duplicate entries for variable stars.

Recently, the variable star search team I lead reported a batch of variable stars to VSX. During the waiting period for inclusion, there’s often uncertainty. Consequently, two variable stars were included in VSX twice. They are:
STSP J212207.73+471345.8 = AISV-BD J320.532+47.229
STSP J190906.59-030335.2 = AISV-BD J287.277-3.059
I checked the reporting times for these two variable stars. Their discovery should be attributed to the AISV-BD team.

Additionally, here are other duplicate variable stars:
V5416 Sgr = Gaia DR3 4050251466911384064

Thanks Jiashuo, I have removed them from VSX.

Cheers,
