摘要：

This paper presents color transformations for Hubble Space Telescope Near Infrared Camera and Multi-Object Spectrometer (NICMOS) camera 2 observations to the ground-based Carnegie image tube photometric system at Cerro Tololo Inter-American Observatory (CIT/CTIO), using observations of 19 moderately bright, red stars in Baade's window in the color range 0.7 < (J-K) < 1.6. We emphasize that these transformations will be accurate only for cool giants of near-solar metallicity. We simulate both NICMOS and ground-based photometry by convolving near-IR spectra taken above the atmosphere with different filter transmission profiles. The results are consistent with our transformation.
