HD 98922 PIONIER and GRAVITY continuum data overview. Top row: Overview diagram summarizing Fig. A.1 and Fig. A.2 and showing array configurations with comparable (u,v) coverage. Each line shows the spatial frequency and PA probed by the longest baseline of a given four-telescope configuration. Two epochs have the same color and line style if they show a similar (u,v) coverage. The gray lines refer to epochs for which the (u,v) coverage cannot be reasonably compared to any other. Numbers identify epochs following Table A.1 and A.2; Middle row: Closure phase signal per epoch and instrument. The spatial frequency chosen is the one for which a strong variation in the CP signal between epochs with a comparable (u,v) plane coverage is observed. Bottom row: Squared visibilities signal for each epoch and instrument, for the same spatial frequency as in the middle row.
