Repeating work just done at LLO (see aLOG 15385 ), I have run some scripts to count the current H1 rates to frame files for commissioning and science frames. I got copies of the channel lists from the 'daqsvn' SVN server. The script syntax is in (attached) commrates_script.txt. acquire=1 got channels only in commissioning frame (attached h1commrates.txt) acquire=3 got channels only in science and commissioning frame (attached h1scirates.txt) I created additional scripts (see attached calc_comm_rates_table_script.txt) to sum things up by sub-system. See attached h1_comm_rates_table.txt, h1_sci_rates_table.txt. Science frames use acquire=3, commissioning have acquire=1,3 I put this into a spreadsheet (attached H1FrameRates_2014-10-29.xls) and tabulated for Commissioning and Science Frames (see PDFs) Of note: The pre-compression rate of 21.50 MB/s is resulting in a compressed rate of over 12 MB/s (which includes all the EPICS channels). If we compare this to the L1 uncompressed rate of 16.91 MB/s, we see that most of the difference (4.6 MB/s) is because the H1 PEM rate is 6.79 MB/s compared to L1's 2.20 MB/s. At H1, PEM rate is greater than all the ISC data.
