Three TESS sectors cover 35.0 to 37.4 percent of transit phases for circular HD 48948 d models with 2 Earth radii and impact parameters 0 and 0.8 at four tested periods
We tested the transit sensitivity of TESS sectors 20, 60, and 73 for HD 48948 c and d. We searched 42,408 valid 120-second samples with single-event templates and local quadratic baselines. No corrected-flux template reaches the preset score of 8; the largest score is 6.4325. For circular models with a radius of 2 Earth radii, exact time-interval unions show that 35.0019 to 37.4030 percent of the phase cycle of d meets the sample-coverage rule. The range covers four tested periods from 150.28 to 153.24 days and impact parameters 0 and 0.8. Coverage for c is 80.4586 to 98.6618 percent at four periods from 37.88 to 38.24 days. A separate grid of 32,768 corrected-flux injections tests four radii and 512 phases per model. Every covered model with a radius of 2 or 3 Earth radii reaches the threshold. Smaller models have incomplete recovery. An added aperture-flux control has 4,096 trials. Large aperture features are weaker in corrected flux; no cause is assigned. Missing observations are the main limit for the tested larger models of d. The continuous coverage measures and finite recovery counts are not confidence limits. They do not establish that either planet fails to transit. The tests assume fixed stellar values and limb darkening, and insert signals after mission processing. We preserve source FITS files, provenance, full score banks, every trial, exact phase intervals, figures, code, and reproduction instructions.

We use its fixed source set and error scale rule. We extend its weighted projection and stellar annulus code to local quadratic baselines, single events, and the outer planets. We also use its source integrity routine and retain the MIT notice.
