Version 9 - 2001-05-21 (CE) |
| 5 |
--------- |
| 6 |
+ issue 9 |
| 7 |
+ this involves the following offsets w.r.t. issue 5: |
| 8 |
|
| 9 |
delta_R_y delta_R_z |
| 10 |
RGS1 +22.3 arcsec +15 arcsec |
| 11 |
|
| 12 |
+ the angles for all instruments are identical, except OM, which |
| 13 |
remains unchanged |
| 14 |
|
| 15 |
Version 8 - 2000-12-18 (CE) |
| 16 |
--------- |
| 17 |
+ issue 8 |
| 18 |
+ unfortunately the angles used for creation of in issue 7 where |
| 19 |
wrong, expect Ry for RGS. Here is the new offsets w.r.t. issue 5: |
| 20 |
|
| 21 |
delta_R_y delta_R_z |
| 22 |
RGS1 +53.6 arcsec +15 arcsec |
| 23 |
EPN -20 arcsec +80 arcsec |
| 24 |
|
| 25 |
|
| 26 |
Version 7 - 2000-09-28 (CE) |
| 27 |
--------- |
| 28 |
+ issue 7 |
| 29 |
+ change of the SIAM angles of all EPIC camera to be at the full |
| 30 |
value of what is desired by EPN. Angles w.r.t. SIAM_0005 are |
| 31 |
|
| 32 |
delta_R_y delta_R_z |
| 33 |
RGS1 +53.6 arcsec -15 arcsec |
| 34 |
EPN +20 arcsec -80 arcsec |
| 35 |
|
| 36 |
+ SIAM angles of RGS are as in Version 6 (minor numerical change |
| 37 |
due to change of program; this was really made for consistency only). |
| 38 |
|
| 39 |
Version 6 - 2000-09-19 (CE) |
| 40 |
--------- |
| 41 |
+ issue 6 |
| 42 |
+ split into RGS and EPIC (pn) SIAM angles; the EPIC angles are an |
| 43 |
intermediate value of what is desired by EPN. |
| 44 |
+ we are shifting the following rotations w.r.t. the previous SIAM |
| 45 |
angles. |
| 46 |
|
| 47 |
delta_R_y delta_R_z |
| 48 |
RGS1 +53.6 arcsec -15 arcsec |
| 49 |
EPN +20 arcsec -15 arcsec |
| 50 |
|
| 51 |
+ from this version onwards we have to provide the SIAM_????.CCF |
| 52 |
which has the format of the BORESIGHT CCF to VILSPA |
| 53 |
+ the values derived for EPN are copied to EMOS1 & EMOS2, those |
| 54 |
found for RGS1 are also copied to RGS2; OM angles are untouched |
| 55 |
|
| 56 |
Version 5 - 2000-06-15 (RM) |
| 57 |
--------- |
| 58 |
+ issue 5 |
| 59 |
+ update only affects OM: centers boresight in OM FOV. |
| 60 |
Needed for correct positioning of fast mode windows. |
| 61 |
boresight averaged over 12 observations |
| 62 |
(based on Alice Breeveld's email Date: Tue, 13 Jun 2000 14:41:20 +0100) |
| 63 |
Distortion correction applied to STR position. |
| 64 |
However there is still an one pixel ambiguity due to mixing of SAS |
| 65 |
and IDL pixel addressing convention. |
| 66 |
|
| 67 |
Version 4 - 2000-02-29 (RM) |
| 68 |
--------- |
| 69 |
+ issue 4 |
| 70 |
+ best estimates for EPIC & OM, no changes for RGS |
| 71 |
+ first use: rev 44 (2000-03-05 07:00:00) |
| 72 |
|
| 73 |
Version 2 - 2000-02-02 (RM) |
| 74 |
--------- |
| 75 |
+ issue 2 |
| 76 |
+ at the request by PX all instruments are put at the same |
| 77 |
pointing to enable the use of the small window mode of MOS |
| 78 |
+ first use: rev 31 (2000-02-08) |
| 79 |
|
| 80 |
Version 1 - 2000-01-26 (RM) |
| 81 |
--------- |
| 82 |
+ only OM updated |
| 83 |
+ never used, as only the OM was updated. |
| 84 |
Version 0.1 - 1900-09-19 (CE) |
| 85 |
----------- |
| 86 |
+ initial version |
