The filters supported by magmax.pro are:
| Band | Keyword | start wavelength [Å] | end wavelength [Å] |
| U | /u | 3000 | 4200 |
| B | /b | 3600 | 5600 |
| V | /v | 4700 | 7000 |
| R | /r | 5500 | 9000 |
| I | /i | 7000 | 9200 |
| J | /j | 10010 | 14976.5 |
| H | /hb | 14501.2 | 18481.2 |
| K (short) | /k | 19000.6 | 23978.8 |
The U, B, V, R and I band filters are data files I got from Peter Nugent. The files used for J, H and K band are NOT the real filters but the simulated response of the ISAAC instrument at ESO's UT1, the first telescope of the VLT, with the particular filter. This data was retrieved from the ESO exposure time calculator at http://www.eso.org/observing/etc/
Also, the K filter is not the full K filter but a short version of it.
