R08.01.01.03-T02 Flag antenna dropouts interactively in plotms

原始指令

In CASA plotms, plot amplitude vs time for the phase calibrator in fixtures/vla_synth.ms (colorized by antenna). Identify antennas/time ranges with dropouts (amplitude near zero) and flag them using Mark Regions and Flag in plotms. Record the flagged antenna/time list in output/flags.csv.

提案难度: 3 / 5

建议验证方式

Grader reads the MS FLAG column: planted dropout visibilities flagged >=95%, good calibrator data flagged <=3%; flags.csv lists the 3 planted antenna/time ranges. Flags must come from plotms: flagdata, flagcmd and the casatools table tool are blocked in the agent's CASA session, and any flagging task call in the CASA log fails.

建议部分得分

50% dropout recall; 30% precision on good data; 20% list correct.

建议验证方式

Grader: final residual RMS <=12 uJy/beam; mask covers the true emission (recall >=0.9) with <=20% of mask area on noise; image flux within 3% of truth. The CASA log must show interactive mask-update events each major cycle; tclean runs with mask files or auto-multithresh are detected in the CASA log and fail.
