	Module	dish
	Tool	dish

Multiply an sdrecord's spectrum by a value or array

Synopsis
scanscale(scan1, sfactor)

Description
This function scales an sdrecord and returns the result as an sdrecord. Also see the function d.scale() to apply scaling to the globalscan1 record directly.

The factor can be a single value, in which case the entire data array in the sdrecord is scaled by one value. The factor can also be an array of values if the user wishes to scale each polarization by a different value. The length of the sfactor array in this case must equal the number of polarizations in the sdrecord to be scaled.

Arguments

scan1		SDRecord to be scaled
		Allowed:	SDRecord
		Default:	no default
sfactor		multiplicative factor
		Allowed:	float or array of floats
		Default:	no default

Returns
Boolean

Example

- sc := d.getc(10)
- scaled := d.scanscale(sc, 2.0)
- d.plotscan(scaled)
- scaled_b := d.scanscale(sc, [2.0,4.5])
- d.plotscan(scaled_b)
