NIRspec
- NIRSpec is equipped with an integral field unit optimized for the spectroscopic study of complex extended objects. It will provide 900 spectra per exposure over a field of view of 3 x 3 arcminutes.（0.6-5mu）
MIRI
- 用CAFE拟合，可以得到9.7mu的尘埃光深
- H2的转动线S(1)-S(7)，可以直接测量H2的含量
- [Ne iii]1.56mu/[Ne ii]12.81mu, which is an indicator of the hardness of the local radiation field
- “The SFR can be estimated with the Pf α, [Ne ii], and [Ne iii] measurements. By assuming a Case B scenario， we translate our Pf α flux to Hα and apply Equation (2) in Murphy et al. (2011) to derive the SFR in our extracted regions.
