This section describes the main updates to HSpot, relevant to all users, which have been made since the release of the updated version for the Open Time Call (OT1) was made (HSpot v5.1). Users are strongly recommended to read this document in conjunction with the HSpot Users' Guide.

2.1. General changes

2.1.1. A note on the upgrade to HSpot 5.2.3

An update has been made to the Versant database manager at HSC, including recent patches to the system. This has required a new operational release of HSpot to link to the modified databases. There should be no visible effect at all for users. No other changes have been made in this version of HSpot.

2.1.2. Other recent changes

  • [PHS-1556] Title of HSpot 5.2.x main window and Proposal Submission Tool window should refer to "OT1 Call Phase 2 Version"

    [PHS-1562] Please update Help for HSpot 5.2 user release.

    [PHS-1560] Minor update to Tip of the Day to keep the information up to date.

    [PHS-1564] Further updates to HSpot on-line Help

    [PHS-1579] Small change to HSpot Help to reflect the changes in overhead calculation for dithered maps.

    Effect:Updates to the online documentation on HSpot to keep it in line with the latest changes.

2.1.3. Other changes

  • [PHS-1520] CLONE -Concatenating dithered observations should have no penalization

    - Implication for user: This has an important impact on dithered maps with SPIRE as, previously, HSpot was adding a slew overhead to each AOR when scan maps were dithered to sample them better. The new implementation of overhead calculation removes this penalisation for taking better maps.

  • [PHS-1577] Wrong computation of overheads?

    - Implication for user: Similar to {PHS-1520]. For dithered maps with PACS no overhead will be applied for scan legs with centres that are separated by less than 3 arcminutes.

  • The Spot Core version incorporated into HSpot 5.2 is now 18.9.19, while HSpot 5.0.4 had 18.9.17. The Spot Core has thus advanced two versions since HSpot 5.0.4.

    - Implication for user: There are some small changes in the appearance of HSpot as well as new, or modified options. New text and screen shots have been incorporated into the HSpot Manual, where required.

  • [PHS-1546] HSpot does not take into account explicit time constraints when calculating AOR visibility.

    - Implication for user: When a time constraint has been added to an AOR HSpot will now show the correct, time-constrained visibility for the observation.

  • [PHS-95] HSpot4.1: AOR overlay does not update the visibility windows.

    - Implication for user: This is an old bug whereby if a constraint is added to an AOR and then the AOR is overlaid on an image, the overlay does not update if the constraint is then modified or removed.
