Nearly 4 years into normal science operations, this JWebbinar will provide an update on the performance and calibration quality of NIRSpec and NIRISS. We will review the status of calibration and pipeline products for each instrument’s observing modes. In the first half of the JWebbinar, NIRSpec will highlight their improvements of their absolute flux calibrations focusing on the IFU, MOS, and FS modes. In the second half, NIRISS will highlight significant improvements for the WFSS mode including trace, wavelength, and photometric calibrations.
