Talk:SREM

SECTION: Space radiation environment monitor. Reviewed by Leonardi on Oct 2013.

REVIEW: This section has been made public with a slightly different name. On the public ES, it is named “radiation environment”.

LM: Hmmmm... This is not what I see when I go to the corresponding page in the public ES

RECOMMENDATIONS:

Please make sure the name of this section is the same in the public and development ES.

I would add the following sentence at the beginning of the page:

“SREM (Standard Radiation Environment Monitor) is a particle detector, developed for space applications. It measures high energy electrons and protons with a fair angular and spectral resolution and provides the host spacecraft with radiation information. SREM was developed and manufactured by oerlikon space in cooperation with Paul Scherrer Institute under a development contract of the European Space Agency. For more information, visit http://srem.web.psi.ch/html/srem_home.shtml.”

LM: There is a section on the satellite page on the SREM and this statement is included there. I think this page should be only about the data. But lets discuss it.

In the “Product description” it is not clear if the midenight to midnight time is UTC. I assume it is but please be explicit.

LM: You are right.

In the “Related products”, the link to the Paul Scherrer Institut asks for username and password. Please remove it or change the link to some public page.

LM: This is public once you register. I've just added a note on this to the text. The registration link is under the data link.

In the “Data files”, please change “…the SREM calibrated data will have…” -> “…the SREM calibrated data have…”

LM: Of course...

In the “Data format”, the tables need to be fixed to reflect the header below:

LM: The tables are absolutely horrible and they will certainly be revised.

For instance, the table CDFITSS2 is very different from the header above. And the sentence “this is a keyword”should disappear, units are in the wrong column, etc. Please fix the tables.
