FTN spectrum

Forums Variable Stars PNV J00425895+4126279 FTN spectrum

We’ve received the calibrated 2D spectrum which was obtained by Richard Miles using the FTN but can’t make much sense of it. One of the FITS files is attached and if anyone has any insight it would be appreciated. According to the FITS header I think the left hand end corresponds to 474.2 nm and the scale is 0.3511 nm/pix. This would put H-alpha at around X=518 but there is no sign of anything there. I need to delve into the FLOYDS documentation but if anyone has any ideas I’d be very pleased to hear them!
