TITLE:   GCN CIRCULAR
NUMBER:  44794
SUBJECT: EP260602a: SVOM/VT optical magnitudes correction
DATE:    26/06/03 08:16:36 GMT
FROM:    Huali Li at at NAOC, SVOM <lhl@nao.cas.cn>

The prior reporting of the magnitudes of EP260602a (Xu et al., GCN 44781) was affected by light blooming near the target. The corrected measurements are as below:

Mid time | Band | Exposure Time | Brightness
9.49 h    VT_B     93*50 s     22.7 +/- 0.2 mag
9.51 h    VT_R     84*50 s     21.5 +/- 0.1 mag

The measurements are in the AB magnitude without correction for Galactic extinction:

We apologize for the errors, and gratefully acknowledge the critical support from the COLIBRÍ team in identifying this discrepancy (Watson et al., GCN 44790).
