The Red Stellar Population in NGC 1569
We present HST NICMOS photometry of the resolved stellar population in the dwarf irregular galaxy NGC 1569. The color-magnitude diagram (CMD) in the F110W and F160W photometric bands contains ∼2400 stars with a formal photometric error ≲0.1 mag down to mF110W ≈ 23.5 and mF160W ≈ 22.5. The fiducial photometry …
