1 Initial discovery spectrum (Zethson et al. 2001).

2 Mar. 13, 2000 observations were accomplished with the F2 ( $0\hbox{$.\!\!^{\prime\prime}$ }85
$) fiducial blocking the $\eta $ Car at the STIS entrance.

3 Repeated spectra from 6480-7000 Å to check for variability.

4 Repeated spectra at 6995-7565 Å to check variability.

5 Mapping spectra were recorded in the 4818-5100 Å with $0\hbox{$.\!\!^{\prime\prime}$ }1$ offsets and 6480-7050 Å spectral range with $0\hbox{$.\!\!^{\prime\prime}$ }25 $ offsets to map the spatial structure of the Homunculus and the Little Homunculus. We used these spectra to estimate the size of the strontium filament in Fe II and [Sr II].

6 Repeated spectra 4194-4593 Å; 4818-5104 Å to check variability.
