SEDm proposals:

• Ariel talking to Shri, conveing numbers from Uli's simulations and details about the physics we are interested.
• Shri said on Wednesday's ZTFtransient telecon that all proposals are science based and thus all science projects should submit their own mag-limited surveys. Therefore we should write our own to show what we would get out of the data.
• Ariel will share what he wrote up for Shri. Half of SEDm time would be required to get to 18.5 mag.
• Without i-band, use of lightcurves is limited but having the spectra and g/R-LCs will help later with photo-typing etc.
• Plan for joint SNIFS/SEDm observation is to supplement SEDm to get to 19-19.5 mag (exact value TBD).
• JN: Lacking an i-band, should we ask for Rainbow camera time? U-band not useful, maybe i-band but probably hard sell.
• MR: When do we release the typing results?
• Foundation is using reported SNe without typing. If we release everything right away, we hand them the SNe but maybe those will be typed anyway (because they are at low-z). However, also currently relying on ASSAS-SN, so they may go deeper when ZTF is running.

SN Ia science validation

• During science validation, we need to see how well we can do our science, e.g. repeatability of standard stars giving various airmasses.
• Should we follow a set of SNe to try SALT fits? Would require someone stepping up.

SWG task chairs

• See main SWG page for proposed list of tasks, which will have to be done throughout the survey.
• The plan is to find someone for each task rather sooner than later.
• The first step will be to come up with the procedure for their task and document this properly, so handing over after a season is as smooth as possible.
• Please step up and volunteer, especially if you are already woring on something related to one of the tasks.

Twiki structure

• For each task/project there should be a page (see the lightcurve simulation page as an example). This page should list all important information and be kept up-to-date. Please also link to telecon minutes if your project was discussed.
• People should not hesitate to edit the SWG's Twiki pages when they find mistakes.
