A survey detection channel overrides the pixels in an astronomical foundation model, and biases tomographic mean redshifts
(翻译)巡天检测通道覆盖天文学基础模型中的像素,并使层析平均红移产生偏置
arXiv:2608.23626v1 Announce Type: new Abstract: Foundation models for astronomy are trained on survey pixels together with the catalogue products derived from those pixels. Those catalogues are incomplete at a measurable rate, and a model trained on both inherits that incompleteness as a systematic.
