Table 1.
Range of redshifts for OH maser lines visible to Apertif.
| OH line | 1430 MHz | 1280 MHz | 1130 MHz |
|---|---|---|---|
| 1612 MHz | 0.12743 | 0.25956 | 0.42675 |
| 1665 MHz | 0.16462 | 0.30110 | 0.47381 |
| 1667 MHz | 0.16599 | 0.30262 | 0.47554 |
| 1720 MHz | 0.20316 | 0.34416 | 0.52259 |
Notes. Apertif observes frequencies up to 1430 MHz, which defines the low redshift limit of the Apertif bandwidth; 1280 MHz is the redshift upper limit for frequencies that are relatively unimpaired by interference; 1130 MHz is the low frequency (high redshift) limit for the Apertif bandwidth.
