add adds two Ultracam frames and outputs a third.
add input1 input2 [coerce] output [nccd nwin]
output = input1 + input2
| input1 | --- | First input frame |
| input2 | --- | Second input frame. The windows of this frame must at least match or enclose those of the first frame. |
| coerce | --- | Coerce the second input file to match the first's format or not. Not always possible: needs binning factors to be correctly related and window start positions to match up correctly. |
| output | --- | Output frame |
| nccd | --- | CCD number if only one to be added, except that 0 means all but then allows a particular window of each CCD to be handled. |
| nwin | --- | Window number if only one to be added. |
