  1. Reduction of AMBER observations of ZCMa • AMBER data from P76 • Telescopes: UT1 – UT2 – UT4 • AMBER in Medium Resolution mode (R = 1500) Target: ZCMa Type: Herbig Be Star Mk = 4.3 Simone Antoniucci, Gianluca LiCausi, Stefan Vehoff

  2. Calibrator: HR2379_B02, mk=2.7

  3. Target: ZCMa , mk=4.5

  4. Averaged Square Visibilities of the Calibrator

  5. Average square Visibilities (uncalibrated) of the Target Extracted with computeAveragedMergedVisibilities Very Noisy !

  6. ZCMa Spectrum Extracted with AMMYORICK procedure: ExtractVis with a “binning” of 1000 frames. Br emission

  7. Remarks • Possibilities to deal with low flux data: • use the proper color table to look at the frames • put a threshold on SNR or flux to choose the best frames to work with, or • use binning to average frames within individual observations • Many thanks to Eric and Florentin for their help!

  8. …by the way: What the hell is this?
