2017B Release Notes

NOTE: The Observing Tool is currently in its Second Public Release. It will produce 1) monocular and binocular LBC Science scripts 2) monocular MODS scripts (which can be run at time of execution in “identical” and “fraternal” twin mode) 3) monocular LUCI1 and LUCI2 Science seeing-limited scripts 4) limited binocular LUCI Science scripts; including “identical twin” OBs, with mirrored observations on both SX and DX, 5) “Fraternal” LUCI twin scripts that allow for different instrument configurations but require identical targets, PAs, and offsets 6) calibration scripts for all instruments. Libraries for all instruments are also available

2017B Version 1.2: Oct 15, 2017

Listed below are known issues and bugs in the Second Public Release. Improvements to this software are on-going and despite our best efforts, all bugs are likely not known or characterized. If you find a bug, please contact the Q-Dev team at queue_dev@lbto.org.

Current Release:

• 2017B V1.2 (10/15/17): Point release of 2017OT

Upgrades/Fixes to previous point releases:

• The lamp settings for Fraternal LUCI arcs are not saved when importing and exporting programs. This has now been resolved and the libraries updated.

• Telescope Mode and PA copy/paste errors between LUCI 1/2 and Fraternal LUCI now resolved

Upgrades/Fixes to previous semester releases:

• Addition of Fraternal LUCI Instrument, Fraternal LUCI Sequencer, Fraternal Calibrations which allow users to specify different instrument configurations as long as the PA, Target, and Telescope Mode are the same

• Addition of ESM Mode to the Telescope Mode Options

Known Issues:

• Warning and error messages for LUCI may not be up-to-date with rapid developments in modes and mechanisms offered. Unless explicitly stated, errors will not prevent script generation and can be safely ignored if you are confident with your set-up. Please check with your ISA if you have any concerns.

• Acquisition and spectroscopy blocks are not properly connected to lock Target coordinates, PA, or GS coordinates so that they must be identical. The same is true for LBCR and LBCB blocks which MUST have the same offsets.

• LBC Focus and Guide Selection: Due to image distortion there is noguaranteethe Guide or Focus chip will land on the desired chip. FOR LBC Blue the image distortion is fairly minimal, for LBC Red, keep the Guide and Focus star on the inner portion of the tech chip overlay (the half closest to the science array) for best results.

• LUCI Guide Probe geometries are not high fidelity (missing fold mirror shadow). Additional geometry will be added in the future.

• On Windows 10, no desktop icon appears after install. The icon does appear in the start menu.

• It is currently impossible to enter 0s as an Exposure Time for either MODS or LBC. Although it is common practice to do so for biases, it is not necessary in the OT. The scripts will simply ignore whatever exposure time you choose.

Known Bugs:

 

• Downloads of the library into Windows sometimes fail with the message shown below. One potential solution is to be sure to import the library directly from the default browser download folder rather than using any browser drag-and-drop feature. Another solution is to close and reopen the OT and try the import again.

• Intermittent screen painting issue across all platforms. The Telescope Mode and Position Angle dropdown boxes may disappear from the Target Tab. If this occurs, you will need to close and re-open your OT.
• Screen painting issues with Windows 10. If you are currently magnifying your desktop using the display settings under Windows 10 you may see cut off text on some OT screen. The ‘Observation’ / script creation panel, and the ‘Random‘ and ‘Grid‘ dialog boxes in the ‘Offset Sequence Component’ panel are known examples of where this may be seen. To correct this right click on your desktop and select ‘Display Settings’ from the menu. Set the ‘Change the size of text, apps, and other items’ slider to 100% and click on ‘Apply’. You may need to log out of your current Windows session and log back in again to have this correctly applied o the OT. If you find this makes the text on your screen too small to read then you might consider reducing your screen resolution under ‘Display Settings’, or using the ‘Magnifier’ desktop application.

• Error messages may appear inappropriately in MODS and LUCI sequence tabs even when no offset iterator is present: “You are offsetting along the dispersion direction and may be dithering outside the slit.” In these instances, please simply ignore this warning

• In LUCI, the OH1060 is not correctly identified as a cross-filter in the error handling software. You may receive warnings about exposure times and/or cross-filter combinations even when you have correctly selected this combination. Please ignore these warnings.

• You may see incorrectly triggered warning messages when completing MODS arcs or flats that suggest that the combination of filters and modes is non-standard. These warnings should only trigger for science; ignore any that appear for calibrations

• The LBC image is too small when fetched from any image server other than the default image server, accessed via the default “image” button.

• Bulk imports of XML files may result in a Java error message

• If the LBC image is too small (see above) it will impact the GS query.

• Selected zoom level in one instrument can affect FOV of other instruments in the Position Editor when switching between observations

• LBC Instrument Tab: When setting the Science Chip Readout, it is possible to put a minimum that is larger than maximum (don’t do this).

• Offset Tab: when manually changing the offsets using the two text boxes at the bottom of the tab (X/Y or RA/Dec) note the extra spaces. Editing may require backspacing, especially to add a negative sign.

• When loading your own FITS file and running catalog search, display of default image may not act as expected. Reproducible and under investigation.

• Use of 2nd Gen DSS @ CADC gives null pointer exceptions.

• Use of DSS v2 infrared @ ESO may give sporadic timeouts.

Previous Release:

• 2017B V1.1 (9/15/17): Point release of 2017OT

Upgrades/Fixes to previous semester releases:

• See details in V1.2 notes.

Known Issues:

• The lamp settings for Fraternal LUCI arcs are not saved when importing and exporting programs. This appears mostly for LUCI2 lamp settings.

• Telescope Mode and PA copy/paste errors between LUCI 1/2 and Fraternal LUCI. It appears that the PA and Mode both go back to default.

• See current release notes for more details.
