Software Release Note for ISOC version 15.2

Dependencies

External dependencies:

Fixed SPRs in core v12.9:

OSS:

SPR 844

The Pattern Calculator (not strictly part of OSS...) now correctly displays the coordinates of the generated pointings in sexagesimal notation, also when the coordinate system is galactic.

Starmap:

SPR 850

For observations with static patterns, Starmap will now show the pointings in the pattern, instead of the coordinates of the source of the observation. For this type of observations (e.g. AOCS calibrations) the "source" of the observation is often not relevant and fabricated.

Implemented SCRs in core v12.9:

PHS:

SCR 622

The size of the window showing the source list on the details panel for subscriptions has been adjusted to a more reasonable size.

OSS:

SCR 597

We have introduced the concept of a "roll angle strategy". This is a property of dynamic patterns, that determines the roll angle of the pointings on the pattern. Every pattern has such a strategy; the old behaviour is reproduced by the strategy "Static". With this setting, all pointings will be generated with the same roll angle (which can be chosen by the user). A new strategy is called "Sequential". When this strategy is selected, the roll angle will step through a pre-defined range (for now defined as from -4 to 4 degrees). The roll angle will step through the range, one step for every cycle through the pattern. If the pattern is a 5x5 raster of which we schedule 75 points, the first 25 will be scheduled with roll angle -4, the second 25 points with roll angle 0 and the last pattern will be scheduled with a roll angle of 4 degrees. The range is defined as a domain property, managable from CCS.

Implemented SCRs in DB v7.7:

SCR 597

A few columns were moved into the FD_PATTERN table: END_PATTERN, POINT_ORDER and PATTERN_CENTER from DYNAMIC_PATTERN and CYCLE_SIZE from PATTERN_CENTER. The reasons are mostly rather technical (it has to do with the order of applying different pattern features). For the cycle size the reason is that the meaning of this property was the number of pointings after which a shift in pattern center would occur. Now the meaning is a little bit more general as it also is the number of pointings after which the roll angle change occurs. If a pattern has a non-static roll angle strategy but no wandering COP, the cycle size cannot be defined in the PATTERN_CENTER table.
