After the calculation, the mean value removed from each jiggle can be added back onto the data - this should protect against removing flux from MAP data.
If a SKY NDF is found in the REDS extension, it is assumed that the sky variation has already been determined (eg by calcsky) and this sky signature is removed. The 'ADD' parameter is ignored in this case.
|nn||A number||5 or 19|
|id||Bolometer id||h7 or c14|
|rn||Ring number||r1 (for the first ring)|
|r5 (for the outer ring of the SHORT array)|
|r-1 (for the outer ring)|
|r-2 (one ring in from outer ring)|
|all||All bolometers||all (select the entire array)|
Each value must be comma separated but can be preceded by a minus sign to remove the bolometer(s) from the list. The definitions of ring number and `all' are dependent on the selected sub-instrument.
Here are some example values for BOLOMETERS:
|[17,18,19,20]||Bolometers 17, 18, 19 and 20|
|[h6,h7,h8,h9]||Bolometers H6, H7, H8, H9|
|[r0]||Ring zero (central pixel)|
|[r0,-19]||No bolometers (bol 19 of LONG is R0/H7)|
|[h7,r1]||inner ring and H7|
|[r1,-h8]||inner ring without H8|
|[r1,-18]||inner ring without bolometer 18|
|[all,-r1,-h7]||all pixels except the inner ring/H7|
|[all,-r3,g1]||all pixels except ring 3 but with|
|G1 (which happens to be in r3)|
|[all,-r1,-r2,-r3,-r4,-r5]||Selects the central pixel|
|[all,-r-1]||Selects all except outer ring|
Note that the bolometer sum is calculated sequentially so that [all,-all,h7] would leave you with bolometer H7.
