BUG:	If the calibration bandpasses are less than a pixel wide the flux
	summation is incorrectly done when both endpoints are within the
	same pixel; the code assumed that the two endpoint pixels were
	not the same.  Generally the calibration data, in onedstds$, has
	much larger bandpasses than typical spectra and so this bug has
	not be seen except in one reported case where a private calibration
	file with very small bandpasses was used.

STATUS:	Fixed in V2.10.  The workarounds are to revise the calibration
	file to larger bandpasses (if using a private version), resample
	the spectra to smaller dispersion, or, the best choice, specify
	the bandpass widths and separations in the task to override the
	calibration file bandpasses and interpolate the calibration file
	data.

BUG:	When using the skyedit option to review and eliminate bad sky
	apertures there is a limit to the number of sky apertures that
	can be retained.  Exceeding this limit can cause the CL to crash.
	The limit is determined by how many aperture
	numbers can be fit into 160 characters in a string of the form
	11,12,13,...; for 2 digit aperture numbers this would be a
	little over 50 sky apertures.  The workarounds are to use less
	than about 50 sky apertures or to not use the sky edit option.

STATUS:	Planned to be fixed in V2.10.2.
