CC NOTE: |
| 89 |
CC when using f_drms_readfits there are two posibilities: |
| 90 |
CC 1.- f_drms_readfits will allocate the header in C so |
| 91 |
CC do NOT double allocate in fortran. The "header" variable |
| 92 |
CC has to be of type allocatable in fortran though. |
| 93 |
CC 2.- f_drms_readfits2 will not allocate in C. You'll need |
| 94 |
CC to pass a local variable of enough size |
| 95 |
CC ************* |
| 96 |
CC Go and read a fits file using the drms_readfits function |
| 97 |
