rebin

Synopsis

Rebin a histogram

Syntax

rebin( x0, x0lo, x0hi, x1lo, x1hi )

Description

The rebin command redistributes a histogram from one resolution to another.

Example

sherpa> arf = get_arf().specresp
sherpa> elo = get_arf().energ_lo
sherpa> ehi = get_arf().energ_hi
sherpa> lo = get_rmf().e_min
sherpa> hi = get_rmf().e_max
sherpa> eff = rebin(arf, elo, ehi, lo, hi) # without normalization
sherpa> width = (hi-lo)
sherpa> ewidth = (ehi-elo)
sherpa> ewidth = ewidth[:len(width)]
sherpa> eff *= (ewidth/width) # normalized

Rebin the ARF from ENERG_LO to E_MIN.
