From the S/N per ramp as calculated above and the total S/N that is required for this observation the number of ramps needed can be calculated using:
The number of ramps calculated using this fomula should be rounded
to the nearest integer number.
As discussed in section 6.1.2., observers are advised to always do
at least 6 scans. The minimum number of ramps therefore is 6. If
is less, the deglitching of the data may not be possible.
