According to TFRRS, the IC4A/ECAC marks have been included in their database. Assuming no one drops out of the top 16 individuals or top-12 relays, the following are going to nationals:
Kept in some other marks within top 20 in case a lot of people drop... unlikely for the relays, but who knows. Also included any alumni qualifiers and any known Ivy records that make the cut.
800m - tied-16th, Erika Veidis (H) - 2:05.70
mile - 2nd, Abbey D'Agostino (D) - 4:30.03 - Ivy record
3000m - 1st - D'Agostino - 8:55.41 - Ivy record
3000m - 12th - Alexi Pappas (Oregon-Dartmouth) - 9:07.97
5000m - 13th - Dan Lowry (Michigan-Brown) - 13:42.48
5000m - 6th - D'Agostino - 15:47.02
5000m - 11th - Rachel Sorna (Cor) - 15:53.76
5000m - 13th - Pappas - 15:54.64
DMR - 2nd - Princeton (Williams, Hollimon, Dinkins, Callahan) - 9:27.74 - Ivy record
HJ - tied-4th, Montez Blair (Cor) - 7-5.25
TJ - tied-14th - Damon McLean (Pr) - 52-3.25

WT - 15th - Adabelle Ekechukwu (H) - 68-4.25 - Ivy record
pentathlon - 8th - Martina Salander (H) - 4094 - Ivy record
I will check this again tomorrow to make sure nothing has changed. But I am surprised by the potential number of Harvard qualifiers (Veidis' time really surprised me).
