Hi All,
There are some slight updates to the 124 draft uploaded to the CWE
(particularly for the Dt and Xt definition for eqs. 14 and 16).
https://cwe.ccsds.org/sls/docs/SLS-DC/CWE%20Private/124.0-B/advances124_spring_to_fall_2021/124x0w6-01091510_wong_evans_hernandez.docx
Please let me know by this Friday if you need more time to review it.
Best,
Mark Wong

Hi Miguel,
I updated that and have loaded the updated document in word and pdf and a
pdf with mark up to the CWE

@Mark do you have any more comments? If not I think it is good to go. What
are the next steps?
Best regards,
Dave

Thank you Dave,
I have now been able to look at the highlighted differences.
My only comment is about eq 20, case 2. The list of valid values could be
written in ascending order, e.g., {max(0, t-V_t), max(0, t-V_t) + 1, ...,
t-1, t}. The reverse order would be fine by me too, but values should be
sorted (unlike now, where it says {t-1, t, ..., max(0, t-V_t)}, which I
think it's not easily interpretable). In eq 14, the order was from
greater to lower; I suggest we are consistent in all equations giving
sequences of time points.
Other than that, I'm satisfied with the draft as it is.
Kind regards,

Dear David and Mark,
Thanks for your effort during summer. I confirm I only see the double t
subindex in eq (16), and a few blank boxes at all in Dave's Aug 30's
message.
I will be happy to review this again if you'd like me to.
In the interest of time and accuracy, would it be possible to get a PDF
file with correct rendering and highlighted differences vs the last
version we iterated?
Thank you very much, have a nice day.

DJE: It is used as it relates to how to calculate Ct which is then needed
to calculate Vt (i.e. Vt = Rt + Ct). One can view Rt as a minimum for Vt
while the maximum is 15. Ct is extra robustness, on top of Rt, that we get
for free when the mask did not update in the cycles from t-Rt to t-Rt-Ct.

Hi Dave,
Somehow I’m not seeing your comments on the uploaded version.
Now I see eq 16 is updated to from Vt to Rt and that indeed simplifies the
equation.
If this is correct, the notes for eq 14 “… (see section 4.2.3) for .
" might not be necessary since it is never been used.

Hi Mark,
I just clicked on the link and it looks OK. Here is a screenshot. Do you
see something different?

Hi Dave,
Can you double check the eq 16 in the latest upload? I only see an
additional subscript t on the Rt in the 1st condition that was edited.

Hi Mark,
Back from holiday...
Thanks for your comments. I accepted the one on eq 14 as is.I
I think your comment on eq 16 can be better solved by introducing a
simplification in the standard (it does not change my code). Please have a
look if this addresses your issue. I put Miguel on copy as he has helped
with the standard enormously and I would like his approval before changing
equations!

edits/comments make any sense.

Dear working group,
The 124 standard has been updated, reviewed and agreed between ESA, CNES
and UAB. It is available in pdf and doc on CWE.
https://cwe.ccsds.org/sls/docs/SLS-DC/CWE%20Private/124.0-B/advances124_spring_to_fall_2021/124x0w6-22071530.docx?d=wde9feb858ce64ba09aa9e41ce0eee1aa

The UAB comments and answers and the previous versions are available there
as well.
Can I ask that any comments the rest of the working group are provided by
the end of August.
It was agreed at the spring meeting that if no major comments are received
then we could start the space agency review process after that point.
Therefore I will contact Mark at the beginning of September if there are
no more changes.
Best regards,
Dave
