[fitsbits] EXPOSURE or OBSTIME?

[Tom Kuiper]

I'm working on a radio spectral line data acquisition package and need to
decide
what keyword to use for integration time. An example FITS file that I have from
the SEST telescope at La Silla uses OBSTIME. The OGIP Spectral File Format
specifies EXPOSURE.  Are there any other keywords in use for this parameter?
Is there any hint of a convergence on a standard?

Thanks
