Download and process any CRISM image, including Radiance or I/F, Short or Long, FRT/HRL/MSP etc.

Arguments and Return Values

Inputs: takes a truncated image id and the desired processing steps

Output: the processed structure including all desired steps elements


Syntax: process_crism(product_id [, sl=BOOL][, raw=BOOL][, resample=BOOL][, atm=INT][, destripe=BOOL][, index=BOOL][, wget=BOOL][,rotate=BOOL][, src&61;BOOL])

product_id - truncated product id. NOTE: Does not include prefix. This should look like 000035B5_07

sl - include the short wavelength (default is 0)

raw - output the entire PDS structures for each component (default is 0)

resample - resample the array to uniform wavelengths across the detector crism_resample() (default is 0)

atm - perform the atmospheric correction crism_atm() Default is 1, Mapping is 2

destripe - remove column related noise and spikes crism_destripe() (default is 1)

index - create the standard indices create_indices() create_indices_key() (default is 1)

wget - force the use of wget rather than copy() (default is 0)

rotate - rotate the image to ~North up (default=1)

src - download the data from the PDS location
