CMBR subtraction

As an alternative to using reference positions on the sky, these checkboxes permit the spectrum of the cosmic microwave background radiation (CMBR) to be subtracted from the spectrum at the on-source position.

The parameters of the monopole and dipole terms adopted for the CMBR are as follows:

	Monopole intensity:	    2.728 K
	Dipole intensity:       3.372 mK
	Coordinates of pole:    264.14d, 48.26d (Galactic)
These are taken from Fixsen et al. (1996).

The monopole and/or dipole checkboxes override any specification of reference positions.
