<p>Data files acquired with the Play Back for different fadc250 data formats are:</p>
<p>run 20374 (standard, mode 9)</p>
<p>run 20375 (standard, raw mode 10)</p>
<p>run 20377 (intermediate compression, mode 9)</p>
<p>run 20379 (full compression, mode 9)</p>
<p>The data format definition is in<br /><a href="https://halldweb.jlab.org/level-1/manuals/FADC250/Programming_FADCV2_V40.pdf">https://halldweb.jlab.org/level-1/manuals/FADC250/Programming_FADCV2_V40...</a></p>
<p>In the play back we define two rectangular pulses for: rocfcal4, slot 3, ch 1 (see below).</p>
<p>Input parameters for Play Back: </p>
<p>BLOCKLEVEL 5<br />
FADC250_NPED 4 (4 samples summed for the baseline. The integral is 4 x 100 = 400)</p>
<p>FADC250_MODE 9 (10 for one file in the list)<br />
FADC250_W_WIDTH 100<br />
FADC250_NSB 3<br />
FADC250_NSA 9<br />
FADC250_NPEAK 3</p>
<p>FADC250_READ_THR 108</p>
<p>Pulse shapes:</p>
