Summary of different follow-up strategies and prospects of an improved analysis technique concerning modeling of microlensing.
| Row | baseline2018a | alt_sched | |
|---|---|---|---|
| LSST + follow-up | 1 | 16.5 (22.4%) | 21.0 (33.9%) |
| Follow-up in bands riz | 2 | 15.0 (20.4%) | 20.2 (32.7%) |
| Follow-up after 2 data points | 3 | 20.0 (27.2%) | 23.0 (37.3%) |
| Daily follow-up | 4 | 19.4 (26.4%) | 23.3 (37.8%) |
| Follow-up every third day | 5 | 13.5 (18.4%) | 18.0 (29.2%) |

| Deeper follow-up (2 mag) | 7 | 37.1 (50.6%) | 34.0 (55.0%) |
| Deeper follow-up (4 mag) | 8 | 39.4 (53.7%) | 37.6 (60.9%) |
| No microlensing | 9 | 35.7 (48.6%) | 33.3 (53.9%) |
| No microl., 1 mag deeper | 10 | 48.4 (65.9%) | 43.2 (69.9%) |
Notes. For the two strategies baseline2018a and alt_sched, the number of LSNe Ia with good quality time-delay measurements over the 10-year survey are shown for each considered scenario, where 100 mock LSNe Ia have been investigated. The percentages in the brackets show how many of the total numbers of LSNe Ia (73.4 for baseline2018a and 61.7 for alt_sched from Table 2) have well measured time delays. The exact definition of “LSST + follow-up” (row 1) is described in the text and the scenarios from rows two to eight are alternative follow-up scenarios detailed in the text. Rows nine and ten are hypothetical numbers interesting for future improved analysis techniques of microlensing.
