The G band stands for all colors: the star's temperature and color change through the cycle, and the page does not show that. +- **Pulsation.** The steps show the light alone. The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The G band stands for all colors: the star's temperature and color change through the cycle, and the page does not show that. +- **Pulsation.** The steps show the light alone. The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The G band stands for all colors: the star's temperature and color change through the cycle, and the page does not show that. +- **Pulsation.** The steps show the light alone. The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The G band stands for all colors: the star's temperature and color change through the cycle, and the page does not show that. +- **Pulsation.** The steps show the light alone. The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The G band stands for all colors: the star's temperature and color change through the cycle, and the page does not show that. +- **Pulsation.** The steps show the light alone. The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The G band stands for all colors: the star's temperature and color change through the cycle, and the page does not show that. +- **Pulsation.** The steps show the light alone. The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·

The G band stands for all colors: the star's temperature and color change through the cycle, and the page does not show that. +- **Pulsation.** The steps show the light alone. The star's color and its size change through the cycle and are not drawn: no published calibration found turns Gaia's two colors into a Cepheid's temperature, and nothing here measures this star's size through the cycle. 10 steps a tenth of a period apart are a display choice; the model between them is continuous. + [Investigation ledger](investigations.json) · [Inputs](source/manifest.json) ·
