2. Activities on each instrument branch



Nestor Espinoza Unknown User (aroy)

NIRISS: NIS-034. Unknown User (aroy) is set to work on the wavelength calibration for SOSS. Initial calibration with an A star (good for < 2 um), real calibration to be done with an M-star. Taking a look at ground-based data right now in order to understand how good models are.



Tony Keyes Unknown User (birkmann)

NIRSpec: 


Sarah Kendrew

MIRI: We had a meeting with the MIRI ramps-to-slopes group, which goes all around the consortium (US+Europe). Led by Jane Morrison. They have been worried about detector issues at large. MIRI detectors have some important behaviour that one has to take care of. One of the examples was first and last frame for MIRI, which is not used in non-TSO observations; but for TSO observations is being used by the pipeline. For relative measurements, this seems okay. But if you want absolute flux calibration, including the last frame impacts on this as this one drops down. The ETC does drop the last frame (so not consistent with the pipeline). Might want to request the ETC to change this (which would increase SNR a bit). Everyone good with this.


Nikolay Nikolov Brian Brooks

Brian Brooks working on starting to work on task 3.1. There is a WG which actually has information on this; in particular, this WG was tasked with compiling information on the ground testing data and their objective (Z_GOAL keyword). This in theory is in MAST (you need sign-offs from Scott Friedmann + leads of the data), so data is retrievable. From the NIRCam side, however, they still have data stored in a disk. Armin Rest has a script which can retrieve information from this, in order to compile TSO-like data. Tony Keyes mentions that NIRSpec has also a lot of data on some external hardrives. Not sure how much of that was retained. Nikolay Nikolov mentions that they don't have subarrays, but just using the full frame to cut subarrays works for our analyses.

Nikolay Nikolov mentions on some progress on JP-1478 ( JP-1478 - Getting issue details... STATUS ). Parameter reference file ready to be included on the pipeline; currently working with Brian Hilbert and Brian Brooks on getting this done. This would solve a significant problem in the pipeline, enabling a full loop on the TSO from the pipeline.


Nikolay Nikolov also mentions work he has been doing with Nestor Espinoza  and Sarah Kendrew on some TSO Helpdesk tickets.
