PULSE_SHAPE:

erd = pulse_shape( erd )

pulse_shape corrects for the aftermath of reset pulses, which is noticeable over more samples than the reset cut-out length:

• reset pulse leaves some slowly decaying charge
• shape is quite independent of signal strength
• => subtract a fixed pulse shape
• small effect, a few bits at most
• relevant only for faint sources
• presently nothing is done (!)

• cal02b: reset pulse correction factors

Help topic: IA derive spd

Alternative: derive your own cal02b with derive_pulse_shape
