25.09.05 45 25 26 28 27 Also, via ESOC, emergency commanding of HEEA 4 after possible MCP problem 26
25.09.05 46 25 26 29 27 25 30 29 26 (see above)
  47 causes confusion at JSOC so not implemented, instead ESOC again save the day by implementing DEPV 48 on both sensors, thus keeping LEEA 4 at 27 as follows
02.10.05 48 25 26 29 27 25 30 29 27
  Next week, levels were as below, so DEPVs in use from pp282 onwards are, confusingly: the HEEA part of 44, and 45 for LEEA
10.10.05   25 26 29 27 25 30 29 28
  Next week, unfortunately the CL4 levels unexpectedly went back to previous DEPV (47 and 48) values, presumably after all the confusion of the previous DEPVs

Obs level in MCP tests is changed to: L1 - 29, L2 - 27, L3 - 31, L4 - 29, H1 - 26, H3 - 30, H4 - 30

Obs level in MCP tests is changed to: L1 - 30, H1 - 28
29.06.14 67 Obs level in MCP tests is changed to: L1 - 31, H1 - 29, L2 - 28, H2 - 31, H3 - 31, L4 - 30, H4 - 31

* New henceforths implemented for sheath and wind ops, two levels below operational (except, erroneously, in the case of HEEA2 - this is crrected in DEPV 26)

** DEPV 33 was not actually needed as the level on the HEEA3 sensor was that in DEPV 28. DEPV 31 was an 'emergency' DEPV applied to pp224 to turn the MCP level down to 27 when HEEA3 had shown a possible HV breakdown, but it was not applied in subsequent pp's. pp225, 226 and 227 used levels put in by hand into the piors so the levels shown here are correct - although this does mean that after the MCP test the HEEA3 level was 29 for 4 hours in pp's 225 and 226
