Flux Conversion Correction

An error in NICMOS ISR-014: Flux Units and NICMOS, has been identified. The conversion of NICMOS flux from MJy steradian-1 into Jy arcsec-2 was stated in this document to be 0.084616. This factor, which shows up in several places in NICMOS literature, is incorrect and the correct conversion factor is 2.35044e-05. Please note this change and correct any fluxes that you may have obtained using the incorrect conversion factor. The following conversion equation is correct and should be used:

Sv[Jy arcsec-2] = Sv[MJy ster-1]x 2.35044e-05.
